(PHP 4, PHP 5, PHP 7, PHP 8)
phpinfo — Muestra información sobre la configuración de PHP
Descripción
Muestra gran cantidad de información sobre el estado actual de PHP. Incluye información sobre las opciones de compilación y extensiones de PHP, versión de PHP, información del servidor y entorno (si se compiló como módulo), entorno PHP, versión del OS, rutas, valor de las opciones de configuración locales y generales, cabeceras HTTP y licencia de PHP.
Como cada sistema se instala diferente phpinfo() se usa comúnmente para revisar opciones de configuración y variables predefinidas disponibles en un sistema dado
phpinfo() también es una valiosa herramienta de depuración ya que contiene todos valores EGPCS (Environment, GET, POST, Cookie, Server).
Parámetros

INFO_MODULES 8 Módulos cargados y sus respectivos parámetros Ver también get_loaded_extensions(). INFO_ENVIRONMENT 16 Información de las variables de entorno. Tambien disponibles en $_ENV. INFO_VARIABLES 32 Muestra todas las variables predefinidas de EGPCS (Environment, GET, POST, Cookie, Server). INFO_LICENSE 64 Información de Licencia de PHP. Ver también el » FAQ de licencia. INFO_ALL -1 Muestra toda la información anterior
Valores devueltos
Devuelve true en caso de éxito o false en caso de error.
Historial de cambios
| Versión | Descripción |
|---|---|
| 5.5.0 | Los GUIDs de logos fueron reemplazados con URIs de datos, por lo que desactivar ahora expose_php no tiene efecto sobre el resutaldo de phpinfo(). Los créditos ahora también han sido embebidos en la salida misma en vez mediante enlaces. |
| 5.2.2 | Se añadió la información del "Fichero de configuración cargado", mientras que anteriormente solo existía "Ruta del fichero de configuración (php.ini). |
Ejemplos
Ejemplo #1 Ejemplo de phpinfo()
<?php
// Muestra toda la información, por defecto INFO_ALL
phpinfo();
// Muestra solamente la información de los módulos.
// phpinfo(8) hace exactamente lo mismo.
phpinfo(INFO_MODULES);
?>Notas
Nota:
En versiones de PHP anteriores a la 5.5.0, las partes de la información que se muestra están deshabilidadas cuando la opción de configuración expose_php está establecida a
off. Esto incluye los logos de PHP y Zend y los créditos.
Nota:
phpinfo() muestra texto plano en lugar de HTML cuando se utiliza en la línea de comandos.

This function parses the phpinfo output to get details about a PHP module.
<?php
/** parse php modules from phpinfo */

$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {

This is a slight modification to the previous code by "code at adspeed dot com" that extracts the PHP modules as an array. I used it on PHP 4.1.2 and it failed as the <h2> tags also had an align="center". So this update changes the regex for those tags:
<?php
/* parse php modules from phpinfo */
function parsePHPModules() {
ob_start();
phpinfo(INFO_MODULES);
$s = ob_get_contents();
ob_end_clean();
$s = strip_tags($s,'<h2><th><td>');
$s = preg_replace('/<th[^>]*>([^<]+)<\/th>/',"<info>\\1</info>",$s);
$s = preg_replace('/<td[^>]*>([^<]+)<\/td>/',"<info>\\1</info>",$s);
$vTmp = preg_split('/(<h2[^>]*>[^<]+<\/h2>)/',$s,-1,PREG_SPLIT_DELIM_CAPTURE);
$vModules = array();
for ($i=1;$i<count($vTmp);$i++) {
if (preg_match('/<h2[^>]*>([^<]+)<\/h2>/',$vTmp[$i],$vMat)) {
$vName = trim($vMat[1]);
$vTmp2 = explode("\n",$vTmp[$i+1]);
foreach ($vTmp2 AS $vOne) {
$vPat = '<info>([^<]+)<\/info>';
$vPat3 = "/$vPat\s*$vPat\s*$vPat/";
$vPat2 = "/$vPat\s*$vPat/";
if (preg_match($vPat3,$vOne,$vMat)) { // 3cols
$vModules[$vName][trim($vMat[1])] = array(trim($vMat[2]),trim($vMat[3]));
} elseif (preg_match($vPat2,$vOne,$vMat)) { // 2cols
$vModules[$vName][trim($vMat[1])] = trim($vMat[2]);
}
}
}
}
return $vModules;
}

This is necessary to obtain a W3C validation (XHTML1.0 Transitionnal)...
phpinfo's output is declared with that DTD :
- "System ID" has the wrong url to validate : "DTD/xhtml1-transitional.dtd" rather than "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
- Some module names contains space and the function's output use the name in anchors as ID and NAME. these attributes can't be validated like that (unique name only).
<?php
ob_start ();
ob_start (); // Capturing
phpinfo (); // phpinfo ()
$info = trim (ob_get_clean ()); // output
// Replace white space in ID and NAME attributes... if exists
$info = preg_replace ('/(id|name)(=["\'][^ "\']+) ([^ "\']*["\'])/i', '$1$2_$3', $info);
$imp = new DOMImplementation ();
$dtd = $imp->createDocumentType (
'html',
'-//W3C//DTD XHTML 1.0 Transitional//EN',
'http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd'
);
$doc = $imp->createDocument (
'http://www.w3.org/1999/xhtml',
'html',
$dtd
);
$doc->encoding = 'utf-8';
$info_doc = new DOMDocument ('1.0', 'utf-8');
/* Parse phpinfo's output
* operator @ used to avoid messages about undefined entities
* or use loadHTML instead
*/
@$info_doc->loadXML ($info);
$doc->documentElement->appendChild ( // Adding HEAD element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('head')->item (0),
true // With all the subtree
)
);
$doc->documentElement->appendChild ( // Adding BODY element to HTML
$doc->importNode (
$info_doc->getElementsByTagName ('body')->item (0),
true // With all the subtree
)
);
// Now you get a clean output and you are able to validate...
/*
echo ($doc->saveXML ());
// OR
echo ($doc->saveHTML ());
*/
// By that way it's easy to add some style declaration :
$style = $doc->getElementsByTagName ('style')->item (0);
$style->appendChild (
$doc->createTextNode (
'/* SOME NEW CSS RULES TO ADD TO THE FUNCTION OUTPUT */'
)
);
// to add some more informations to display :
$body = $doc->getElementsByTagName ('body')->item (0);
$element = $doc->createElement ('p');
$element->appendChild (
$doc->createTextNode (
'SOME NEW CONTENT TO DISPLAY'
)
);
$body->appendChild ($element);
// to add a new header :
$head = $doc->getElementsByTagName ('head')->item (0);
$meta = $doc->createElement ('meta');
$meta->setAttribute ('name', 'author');
$meta->setAttribute ('content', 'arimbourg at ariworld dot eu');
$head->appendChild ($meta);
// As you wish, take the rest of the output and add it for debugging
$out = ob_get_clean ();
$pre = $doc->createElement ('div'); // or pre
$pre->setAttribute ('style', 'white-space: pre;'); // for a div element, useless with pre
$pre->appendChild ($doc->createTextNode ($out));
$body->appendChild ($pre);
$doc->formatOutput = true; // For a nice indentation
$doc->saveXML ();
?>
All that could be done with only RegExp but I prefer the use of DOM for manipulating documents

After reading and trying various functions, I couldn't find one that correctly parses all the configurations, strips any left-over html tag and converts special characters into UTF8 (e.g. ' into '), so I created my own by improving on the existing ones:
function phpinfo2array() {
$entitiesToUtf8 = function($input) {
// http://php.net/manual/en/function.html-entity-decode.php#104617
return preg_replace_callback("/(&#[0-9]+;)/", function($m) { return mb_convert_encoding($m[1], "UTF-8", "HTML-ENTITIES"); }, $input);
};
$plainText = function($input) use ($entitiesToUtf8) {
return trim(html_entity_decode($entitiesToUtf8(strip_tags($input))));
};
$titlePlainText = function($input) use ($plainText) {
return '# '.$plainText($input);
};
ob_start();
phpinfo(-1);
$phpinfo = array('phpinfo' => array());
// Strip everything after the <h1>Configuration</h1> tag (other h1's)
if (!preg_match('#(.*<h1[^>]*>\s*Configuration.*)<h1#s', ob_get_clean(), $matches)) {
return array();
}
$input = $matches[1];
$matches = array();
if(preg_match_all(
'#(?:<h2.*?>(?:<a.*?>)?(.*?)(?:<\/a>)?<\/h2>)|'.
'(?:<tr.*?><t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>(?:<t[hd].*?>(.*?)\s*</t[hd]>)?)?</tr>)#s',
$input,
$matches,
PREG_SET_ORDER
)) {
foreach ($matches as $match) {
$fn = strpos($match[0], '<th') === false ? $plainText : $titlePlainText;
if (strlen($match[1])) {
$phpinfo[$match[1]] = array();
} elseif (isset($match[3])) {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$fn($match[2])] = isset($match[4]) ? array($fn($match[3]), $fn($match[4])) : $fn($match[3]);
} else {
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $fn($match[2]);
}
}
}
return $phpinfo;
}
The output looks something like this (note the headers are also included but are prefixed with '# ', e.g. '# Directive'):

To extract all of the data from phpinfo into a nested array:
<?php
ob_start();
phpinfo();
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER))
foreach($matches as $match)
if(strlen($match[1]))
$phpinfo[$match[1]] = array();
elseif(isset($match[3]))
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
else
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
?>
Some examples of using individual values from the array:
<?php
echo "System: {$phpinfo['phpinfo']['System']}<br />\n";
echo "Safe Mode: {$phpinfo['PHP Core']['safe_mode'][0]}<br />\n";
echo "License: {$phpinfo['PHP License'][0]}<br />\n";
?>
To display everything:
<?php
foreach($phpinfo as $name => $section) {
echo "<h3>$name</h3>\n<table>\n";
foreach($section as $key => $val) {
if(is_array($val))
echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
elseif(is_string($key))
echo "<tr><td>$key</td><td>$val</td></tr>\n";
else
echo "<tr><td>$val</td></tr>\n";
}
echo "</table>\n";
}
?>
Note: In order to properly retrieve all of the data, the regular expression matches table headers as well as table data, resulting in 'Local Value' and 'Global Value' showing up as 'Directive' entries.

Removes sensitive data like AUTH_USER and AUTH_PASSWORD from the phpinfo output:
<?php
// start output buffering
ob_start();
// send phpinfo content
phpinfo();
// get phpinfo content
$html = ob_get_contents();
// flush the output buffer
ob_end_clean();
// remove auth data
if (isset($_SERVER['AUTH_USER'])) $html = str_replace($_SERVER['AUTH_USER'], '<i>no value</i>', $html);
if (isset($_SERVER['AUTH_PASSWORD'])) $html = str_replace($_SERVER['AUTH_PASSWORD'], '<i>no value</i>', $html);
echo $html;

Hi.
Here my version of saving php_info into an array:
<?php
function phpinfo_array()
{
ob_start();
phpinfo();
$info_arr = array();
$info_lines = explode("\n", strip_tags(ob_get_clean(), "<tr><td><h2>"));
$cat = "General";
foreach($info_lines as $line)
{
// new cat?
preg_match("~<h2>(.*)</h2>~", $line, $title) ? $cat = $title[1] : null;
if(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = $val[2];
}
elseif(preg_match("~<tr><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td><td[^>]+>([^<]*)</td></tr>~", $line, $val))
{
$info_arr[$cat][$val[1]] = array("local" => $val[2], "master" => $val[3]);
}
}
return $info_arr;
}
// example:
echo "<pre>".print_r(phpinfo_array(), 1)."</pre>";

big thanx 2 Mardy dot Hutchinson at gmail dot com
very good!
some fixes to correct result displaying:
1. we need to trim $matches [1], 'cause there can be empty lines;
2. not bad to remove <body> tag 'cause styles for it not apply correctly...
3. ...and change styles a little (remove "body" selector)
we need to change two lines:
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
?>
to
<?php
preg_match ('%<style type="text/css">(.*?)</style>.*?<body>(.*?)</body>%s', ob_get_clean(), $matches);
?>
and
<?php
preg_split( '/\n/', $matches[1] )
?>
to
<?php
preg_split( '/\n/', trim(preg_replace( "/\nbody/", "\n", $matches[1])) )
?>
That's all! Now we have a really flexible addition to phpinfo();

One note on the above functions for cleaning up the phpinfo() HTML and throwing it into an array data structure. In order to catch all of the info tidbits the preg_match_all has to be tweaked to deal with 2 and 3 column tables.
I have changed the preg_match_all() here so that the last <td></td> is optional
<?php
function parsePHPConfig() {
ob_start();
phpinfo(-1);
$s = ob_get_contents();
ob_end_clean();
$a = $mtc = array();
if (preg_match_all('/<tr><td class="e">(.*?)<\/td><td class="v">(.*?)<\/td>(:?<td class="v">(.*?)<\/td>)?<\/tr>/',$s,$mtc,PREG_SET_ORDER))
foreach($mtc as $v){
if($v[2] == '<i>no value</i>') continue;
$a[$v[1]] = $v[2];
}
}
return $a;
}
?>

One note on the very useful example by "jon at sitewizard dot ca".
The following statements:
Statement 1:
$phpinfo[end(array_keys($phpinfo))][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2:
$phpinfo[end(array_keys($phpinfo))][] = $match[2];
These two lines will produce the error "Strict Standards: Only variables should be passed by reference in...". The root of the error is in the incorrect use of the end() function. The code works but thows the said error.
To address this try using the following statements:
Statement 1 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
Statement 2 revision:
$keys = array_keys($phpinfo);
$phpinfo[end($keys)][] = $match[2];
This fixes the error.
To wrap it all in an example:
<?php
function quick_dev_insights_phpinfo() {
ob_start();
phpinfo(11);
$phpinfo = array('phpinfo' => array());
if(preg_match_all('#(?:<h2>(?:<a name=".*?">)?(.*?)(?:</a>)?</h2>)|(?:<tr(?: class=".*?")?><t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>(?:<t[hd](?: class=".*?")?>(.*?)\s*</t[hd]>)?)?</tr>)#s', ob_get_clean(), $matches, PREG_SET_ORDER)){
foreach($matches as $match){
if(strlen($match[1])){
$phpinfo[$match[1]] = array();
}elseif(isset($match[3])){
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][$match[2]] = isset($match[4]) ? array($match[3], $match[4]) : $match[3];
}else{
$keys1 = array_keys($phpinfo);
$phpinfo[end($keys1)][] = $match[2];
}
}
}
if(! empty($phpinfo)){
foreach($phpinfo as $name => $section) {
echo "<h3>$name</h3>\n<table class='wp-list-table widefat fixed pages'>\n";
foreach($section as $key => $val){
if(is_array($val)){
echo "<tr><td>$key</td><td>$val[0]</td><td>$val[1]</td></tr>\n";
}elseif(is_string($key)){
echo "<tr><td>$key</td><td>$val</td></tr>\n";
}else{
echo "<tr><td>$val</td></tr>\n";
}
}
}
echo "</table>\n";
}else{
echo "<h3>Sorry, the phpinfo() function is not accessable. Perhaps, it is disabled<a href='http://php.net/manual/en/function.phpinfo.php'>See the documentation.</a></h3>";
}
}
?>
Frankly, I went thought the trouble of adding this note because the example by "jon at sitewizard dot ca" is probably the best on the web, and thought it unfortunate that it throws errors. Hope this is useful to someone.

Embedding phpinfo within your page, that already has style information:
The phpinfo output is wrapped within a <div class='phpinfodisplay'>, and we privatize all the style selectors that phpinfo() creates.
Yes, we cheat on preparing the selector list.
<?php
ob_start();
phpinfo();
preg_match ('%<style type="text/css">(.*?)</style>.*?(<body>.*</body>)%s', ob_get_clean(), $matches);
# $matches [1]; # Style information
# $matches [2]; # Body information
echo "<div class='phpinfodisplay'><style type='text/css'>\n",
join( "\n",
array_map(
create_function(
'$i',
'return ".phpinfodisplay " . preg_replace( "/,/", ",.phpinfodisplay ", $i );'
),
preg_split( '/\n/', $matches[1] )
)
),
"</style>\n",
$matches[2],
"\n</div>\n";
?>
Perhaps one day the phpinfo() function will be modified to output such a safe string on its own.

here you can notice that these numeric values of phpinfo
are similar to certain things in the binary system:
-1, coded in 7 digits:
111 1111
look at this:
1+2+4+8+16+32+64=127
unsigned,127 is:
111 1111
so, take a look at this: the way to get all function is to add all of them. zero is nothing.-1 is all.
so you can pass option with a negative number.
for example:
<?php phpinfo(48) ?>
is also:
<?php phpinfo(-80) ?>
48 = 32 + 16
-80= 0 - 64 - 8 - 4 - 2 - 1
so you can see in negative mode it like that:
not nothing
not all (-1) don't forget it !
not option 64
not option 8
not option 4
not option 2
so, that's good if you don't want option 8, you will do this:
not nothing(0)
not all(-1)
not option 8(-1)
you got:
<?php phpinfo(-9); ?>
hope this will be useful, that's my 1rst post ^^

Building on SimonD's elegant example to hide the logged-in username and password, which otherwise appear in plain text, the following should work for PHP 5.4+:
<?php
// start output buffering
ob_start();
// send phpinfo content
phpinfo();
// get phpinfo content
$html = ob_get_contents();
// flush the output buffer
ob_end_clean();
// remove auth data
if ( isset( $_SERVER[ 'PHP_AUTH_USER' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_USER' ], '[ protected ]' , $html);
if ( isset( $_SERVER[ 'PHP_AUTH_PW' ] ) ) $html = str_replace( $_SERVER[ 'PHP_AUTH_PW' ], '[ protected ]' , $html);
echo $html;
?>
To remove additional items, just add them as above.

I needed a way to quickly scroll through the phpinfo which is a large list of information. so here it is. In the top there is a list with sections, the new section loaded extensions will hold the links to the anchors of the loaded modules. the section session variables will show the current loaded sessions. It's using Domdocument for manipulation so you should have that loaded:
<?php
ob_start();
$exts = get_loaded_extensions();
phpinfo();
$phpinfo = ob_get_contents();
ob_end_clean();
//print $phpinfo;
$html_str = $phpinfo;
$html = new DOMDocument();
$html->loadHTML($html_str);
$title = $html->getElementsByTagName("title")->item(0);
$title->nodeValue = "PHP Version ".phpversion();
$body = $html->getElementsByTagName("body")->item(0);
$body->setAttribute("style", "background-color:beige;");
$table = $body = $html->getElementsByTagName("table")->item(3)->nextSibling;
$head = $html->getElementsByTagName("table")->item(0)->nextSibling;
ob_start();
?>
<h2><a name="session_variables">Session variables</a></h2>
<table border="0" cellpadding="2" width="600">
<tr class="h"><th>Variables</th><th>Value</th></tr>
<?php foreach($_SESSION as $key=>$value){
if(is_bool($value)){
$value = ($value)?"true":"false";
}else if(is_array($value)){
$value = '<pre>'.print_r($value, true).'</pre>';
}else if(empty($value) && $value != "0"){
$value = "<i>no value</i>";
}
?>
<tr>
<td class="e"><?=$key?></td>
<td class="v"><?=$value?></td>
</tr>
<?php
}
?>
</table>
<h2><a name="loaded_extensions">loaded extensions</a></h2>
<table border="0" cellpadding="2" width="600">
<tr class="h"><th>Extension</th><th>Version</th></tr>
<?php
natcasesort($exts);
foreach($exts as $value){
$version = phpversion($value);
?>
<tr>
<td class="e" style="width:150px;"><a href="#module_<?=$value?>" style="color:black; background-color:#ccccff;"><?=$value?></a></td>
<td class="v"><?=(!empty($version))?$version:"<i>Unknown</i>" ?></td>
</tr>
<?php
}
?>
</table><br />
<?php
$txt_str = ob_get_contents();
ob_end_clean();
$txt = new DOMDocument();
$txt->loadHTML($txt_str);
$txt_body = $txt->getElementsByTagName("body")->item(0);
foreach($txt_body->childNodes as $child){
$child = $html->importNode($child, true);
$table->parentNode->insertBefore($child, $table);
}
$h2 = $html->getElementsByTagName("h2");
foreach($h2 as $item){
if($item->getElementsByTagName("a")->length == 0){
$value = $item->nodeValue;
$item->nodeValue = "";
$a = $html->createElement("a");
$a->setAttribute("name", strtolower(str_replace(" ", "_", $value)));
$a->nodeValue = $value;
$item->appendChild($a);
}
$a = $item->getElementsByTagName("a")->item(0);
if(!in_array($a->nodeValue, $exts)){
$menu[strtolower(str_replace(" ", "_", $a->nodeValue))] = $a->nodeValue;
}
$top_a = $html->createElement("a");
if(!in_array($a->nodeValue, $exts)){
$txt = $html->createTextNode("(Go to top)");
$top_a->appendChild($txt);
$top_a->setAttribute("href", "#");
}else{
$txt = $html->createTextNode("(Go to extensionlist)");
$top_a->appendChild($txt);
$top_a->setAttribute("href", "#loaded_extensions");
}
$top_a->setAttribute("style", "background-color:beige; font-size:12px; margin-left:5px; margin-top:-5px; color:black;");
$item->appendChild($top_a);
}
ob_start();
?>
<br />
<table border="0" cellpadding="2" width="600">
<tr class="h"><th colspan="2">Sections</th></tr>
<tr>
<?php
$i = 0;
foreach($menu as $key=>$item){
print "<td class='v'><a href='#$key' style='background-color:#cccccc; color:black;'>$item</a></td>";
if($i%2){
print '</tr><tr>';
}
$i++;
}
if($i%2){
print '<td class="v"></td>';
}
?>
</tr>
</table>
<?php
$txt_str = ob_get_clean();
$txt = new DOMDocument();
$txt->loadHTML($txt_str);
$txt_body = $txt->getElementsByTagName("body")->item(0);

I wanted a simple *function* to convert the output of phpinfo into an array. Here's what I came up with thanks to alot of the previous authors tips, and the source file: php-5.2.6/ext/standard/info.c
Call this function like phpinfo_array() prints the array, phpinfo_array(1) returns the array for your own processing.
== Sample Output ==
[PHP Configuration] => Array
(
[PHP Version] => 5.2.6
[PHP Egg] => PHPE9568F34-D428-11d2-A769-00AA001ACF42
[System] => Linux askapache 2.6.22.19-grsec3
[Build Date] => Nov 11 2008 13:09:07
[Configure Command] => ./configure --prefix=/home/grsec/bin/php
[Server API] => FastCGI
[IPv6 Support] => enabled
[Zend Egg] => PHPE9568F35-D428-11d2-A769-00AA001ACF42
[PHP Credits Egg] => PHPB8B5F2A0-3C92-11d3-A3A9-4C7B08C10000
)
[mbstring] => Array
(
[mbstring.http_input] => pass
[mbstring.internal_encoding] => Array
(
[0] => ISO-8859-1
[1] => no value
)
[mbstring.language] => neutral
)
[mcrypt] => Array
(
[Version] => 3.5.7
[Api No] => 20031217
)
<?php
function phpinfo_array($return=false){
/* Andale! Andale! Yee-Hah! */
ob_start();
phpinfo(-1);
$pi = preg_replace(
array('#^.*<body>(.*)</body>.*$#ms', '#<h2>PHP License</h2>.*$#ms',
'#<h1>Configuration</h1>#', "#\r?\n#", "#</(h1|h2|h3|tr)>#", '# +<#',
"#[ \t]+#", '# #', '# +#', '# class=".*?"#', '%'%',
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)" alt="PHP Logo" /></a>'
.'<h1>PHP Version (.*?)</h1>(?:\n+?)</td></tr>#',
'#<h1><a href="(?:.*?)\?=(.*?)">PHP Credits</a></h1>#',
'#<tr>(?:.*?)" src="(?:.*?)=(.*?)"(?:.*?)Zend Engine (.*?),(?:.*?)</tr>#',
"# +#", '#<tr>#', '#</tr>#'),
array('$1', '', '', '', '</$1>' . "\n", '<', ' ', ' ', ' ', '', ' ',
'<h2>PHP Configuration</h2>'."\n".'<tr><td>PHP Version</td><td>$2</td></tr>'.
"\n".'<tr><td>PHP Egg</td><td>$1</td></tr>',
'<tr><td>PHP Credits Egg</td><td>$1</td></tr>',
'<tr><td>Zend Engine</td><td>$2</td></tr>' . "\n" .
'<tr><td>Zend Egg</td><td>$1</td></tr>', ' ', '%S%', '%E%'),
ob_get_clean());
$sections = explode('<h2>', strip_tags($pi, '<h2><th><td>'));
unset($sections[0]);
$pi = array();
foreach($sections as $section){
$n = substr($section, 0, strpos($section, '</h2>'));
preg_match_all(
'#%S%(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?(?:<td>(.*?)</td>)?%E%#',
$section, $askapache, PREG_SET_ORDER);
foreach($askapache as $m)
$pi[$n][$m[1]]=(!isset($m[3])||$m[2]==$m[3])?$m[2]:array_slice($m,2);
}
return ($return === false) ? print_r($pi) : $pi;
}
?>

Simple JS snippet to print phpinfo() inline with it's styles renamed. Thus leaving the container page unaffected and pretty.
<script>
document.write(`<div id="phpinfo"><?php phpinfo(61) ?></div>`);
var x = document.querySelector('#phpinfo > style');
x.innerText = x.innerText.replaceAll('\n', '#phpinfo ');
</script>

If you are embeding the output of the function within a page, the <html> tag can collide and page will distort.
Rather, it is important to extract the contents within the <body> and </body> tags only. Here is how.
<?php
public function info()
{
ob_start();
phpinfo();
$info = ob_get_clean();
$info = preg_replace("/^.*?\<body\>/is", "", $info);
$info = preg_replace("/<\/body\>.*?$/is", "", $info);
echo $info;
}
?>
