htmlentities

(PHP 4, PHP 5, PHP 7, PHP 8)

htmlentities — Wandelt alle geeigneten Zeichen in entsprechende HTML-Entities um

Beschreibung

htmlentities(
    string $string,
    int $flags = ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401,
    ?string $encoding = null,
    bool $double_encode = true
): string

Diese Funktion unterscheidet sich nur dadurch von htmlspecialchars(), dass sie wirklich alle Zeichen, die entsprechende HTML-Entities haben, in diese Entsprechungen umwandelt. Mit der Funktion get_html_translation_table() kann die Übersetzungstabelle auf Basis der angegebenen flags-Konstanten abgefragt werden.

Sollen im umgekehrten Fall stattdessen HTML-Entities dekodiert werden, kann die Funktion html_entity_decode() verwendet werden.

Parameter-Liste

string

Die Eingabezeichenkette.

flags

Eine Bitmaske von einem oder mehreren der folgenden Flags, die die Behandlung von Anführungszeichen, ungültigen Zeichenketten und den genutzten Dokumententyp festlegen. Der Standardwert ist ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401.

**Verfügbare `flags`-Konstanten**
Name der Konstante	Beschreibung
`ENT_COMPAT`	Wandelt doppelte Anführungszeichen um und lässt einfache Anführungszeichen unverändert.
`ENT_QUOTES`	Wandelt sowohl doppelte als auch einfache Anführungszeichen um.
`ENT_NOQUOTES`	Lässt sowohl doppelte als auch einfache Anführungszeichen unverändert.
`ENT_IGNORE`	Verwirft ungültige Code-Unit-Sequenzen anstatt eine leere Zeichenkette zurückzugeben. Die Nutzung dieser Option ist nicht empfehlenswert, da sie » Auswirkungen auf die Sicherheit haben kann.
`ENT_SUBSTITUTE`	Ersetzt ungültige Code-Unit-Sequenzen mit dem Unicode-Ersatzzeichen U+FFFD (UTF-8) oder &#FFFD; (andernfalls).
`ENT_DISALLOWED`	Ersetzt Codepoints, welche in dem angegebenen Dokumenttyp ungültig sind, mit dem Unicode-Ersatzzeichen U+FFFD (UTF-8) oder &#FFFD; (andernfalls), anstatt sie zu belassen wie sie sind. Dies kann zum Beispiel nützlich sein, um die Wohlgeformtheit von XML-Dokumenten mit eingebetteten externen Inhalten sicherzustellen.
`ENT_HTML401`	Behandle Code als HTML 4.01.
`ENT_XML1`	Behandle Code als XML 1.
`ENT_XHTML`	Behandle Code als XHTML.
`ENT_HTML5`	Behandle Code als HTML 5.

encoding

Ein optionaler Parameter, der die Zeichenkodierung für eine Konvertierung definiert.

Wird der Parameter encoding ausgelassen, so wird der Wert der Konfigurationsoption default_charset als Standardwert dafür verwendet.

Obwohl dieser Parameter technisch gesehen optional ist, wird dringend empfohlen, den korrekten Wert für den jeweiligen Code anzugeben, falls die Konfigurationsoption default_charset für die jeweilige Eingabe möglicherweise falsch gesetzt ist.

Die folgenden Zeichensätze werden unterstützt:

**Unterstützte Zeichensätze**
Zeichensatz	Alias	Beschreibung
ISO-8859-1	ISO8859-1	Westeuropäisch, Latin-1.
ISO-8859-5	ISO8859-5	Wenig verwendeter kyrillischer Zeichensatz (Latin/Cyrillic).
ISO-8859-15	ISO8859-15	Westeuropäisch, Latin-9. Enthält das Euro-Zeichen sowie französische und finnische Buchstaben, die in Latin-1(ISO-8859-1) fehlen.
UTF-8		ASCII-kompatibles Multi-Byte 8-Bit Unicode.
cp866	ibm866, 866	DOS-spezifischer kyrillischer Zeichensatz.
cp1251	Windows-1251, win-1251, 1251	Windows-spezifischer kyrillischer Zeichensatz.
cp1252	Windows-1252, 1252	Windows spezifischer Zeichensatz für westeuropäische Sprachen.
KOI8-R	koi8-ru, koi8r	Russisch.
BIG5	950	Traditionelles Chinesisch, hauptsächlich in Taiwan verwendet.
GB2312	936	Vereinfachtes Chinesisch, nationaler Standard-Zeichensatz.
BIG5-HKSCS		Big5 mit Hongkong-spezifischen Erweiterungen; traditionelles Chinesisch.
Shift_JIS	SJIS, SJIS-win, cp932, 932	Japanisch
EUC-JP	EUCJP, eucJP-win	Japanisch
MacRoman		Zeichensatz, der von Mac OS verwendet wurde.
`''`		Eine leere Zeichenkette aktiviert die Erkennung durch die Kodierung des Skripts (Zend multibyte), default_charset und die aktuelle Sprachumgebung (siehe nl_langinfo() und setlocale()), in dieser Reihenfolge. Nicht empfehlenswert.

Hinweis: Weitere Zeichensätze sind nicht implementiert. Statt dessen wird die Standard-Kodierung verwendet und eine Warnung ausgegeben.

double_encode

Wenn double_encode ausgeschaltet ist, verändert PHP keine bereits vorhandenen HTML-Entities. Standardmäßig wird jedoch alles umgewandelt.

Rückgabewerte

Gibt die kodierte Zeichenkette zurück.

Enthält string eine in dem übergebenen encoding ungültige Code-Unit-Sequenz, wird eine leere Zeichenkette zurückgegeben, sofern weder das ENT_IGNORE- noch das ENT_SUBSITUTE-Flag gesetzt sind.

Changelog

Version	Beschreibung
8.1.0	`flags` geändert von `ENT_COMPAT` zu `ENT_QUOTES` \| `ENT_SUBSTITUTE` \| `ENT_HTML401`.
8.0.0	`encoding` ist jetzt nullable (akzeptiert den `null`-Wert).

Beispiele

Beispiel #1 Ein htmlentities()-Beispiel

<?php
$str = "Ein 'Anführungszeichen' ist <b>fett</b>";

// Gibt aus: Ein 'Anf&uuml;hrungszeichen' ist &lt;b&gt;fett&lt;/b&gt;
echo htmlentities($str);

// Gibt aus: Ein &#039;Anf&uuml;hrungszeichen&#039; ist &lt;b&gt;fett&lt;/b&gt;
echo htmlentities($str, ENT_QUOTES);
?>

Beispiel #2 Verwendung von ENT_IGNORE

<?php
$str = "\x8F!!!";

// Gibt eine leere Zeichenkette aus
echo htmlentities($str, ENT_QUOTES, "UTF-8");

// Gibt "!!!" aus
echo htmlentities($str, ENT_QUOTES | ENT_IGNORE, "UTF-8");
?>

An important note below about using this function to secure your application against Cross Site Scripting (XSS) vulnerabilities.

When printing user input in an attribute of an HTML tag, the default configuration of htmlEntities() doesn't protect you against XSS, when using single quotes to define the border of the tag's attribute-value. XSS is then possible by injecting a single quote:

<?php
$_GET['a'] = "#000' onload='alert(document.cookie)";
?>

XSS possible (insecure):

<?php
$href = htmlEntities($_GET['a']);
print "<body bgcolor='$href'>"; # results in: <body bgcolor='#000' onload='alert(document.cookie)'>
?>

Use the 'ENT_QUOTES' quote style option, to ensure no XSS is possible and your application is secure:

<?php
$href = htmlEntities($_GET['a'], ENT_QUOTES);
print "<body bgcolor='$href'>"; # results in: <body bgcolor='#000&#039; onload=&#039;alert(document.cookie)'>
?>

The 'ENT_QUOTES' option doesn't protect you against javascript evaluation in certain tag's attributes, like the 'href' attribute of the 'a' tag. When clicked on the link below, the given JavaScript will get executed:

<?php
$_GET['a'] = 'javascript:alert(document.cookie)';
$href = htmlEntities($_GET['a'], ENT_QUOTES);
print "<a href='$href'>link</a>"; # results in: <a href='javascript:alert(document.cookie)'>link</a>
?>

I've seen lots of functions to convert all the entities, but I needed to do a fulltext search in a db field that had named entities instead of numeric entities (edited by tinymce), so I searched the tinymce source and found a string with the value->entity mapping. So, i wrote the following function to encode the user's query with named entities.

The string I used is different of the original, because i didn't want to convert ' or ". The string is too long, so I had to cut it. To get the original check TinyMCE source and search for nbsp or other entity ;)

<?php

$entities_unmatched = explode(',', '160,nbsp,161,iexcl,162,cent, [...] ');
$even = 1;
foreach($entities_unmatched as $c) {
    if($even) {
        $ord = $c;
    } else {
        $entities_table[$ord] = $c;
    }
    $even = 1 - $even;
}

function encode_named_entities($str) {
    global $entities_table;
    
    $encoded_str = '';
    for($i = 0; $i < strlen($str); $i++) {
        $ent = @$entities_table[ord($str{$i})];
        if($ent) {
            $encoded_str .= "&$ent;";
        } else {
            $encoded_str .= $str{$i};
        }
    }
    return $encoded_str;
}

The flag ENT_HTML5 also strips newline chars like \n with htmlentities while htmlspecialchars is not affected by that.

If you want to use nl2br on that string afterwards you might end up searching the problem like i did. This does not apply to other flags like e.g. ENT_XHTML which confused me.

Tested this with PHP 5.4 / 5.5 / 5.6-dev with same results, so it seems that this is an intended "feature".

If you are building a loadvars page for Flash and have problems with special chars such as " & ", " ' " etc, you should escape them for flash:



Try trace(escape("&")); in flash' actionscript to see the escape code for &;



% = %25

& = %26

' = %27



<?php

function flashentities($string){

return str_replace(array("&","'"),array("%26","%27"),$string);

}

?>



Those are the two that concerned me. YMMV.

htmlentities seems to have changed at some point between version 5.1.6 and 5.3.3, such that it now returns an empty string for anything containing a pound sign:

$ php -v
PHP 5.1.6 (cli) (built: May 22 2008 09:08:44)
$ php -r "echo htmlentities('£hello', null, 'utf-8');"
&pound;hello
$

$ php -v
PHP 5.3.3 (cli) (built: Aug 19 2010 12:07:49)
$ php -r "echo htmlentities('£hello', null, 'utf-8');"
$

(Returns an empty string the second time)

Just a heads up.

Note that you'll have use htmlentities() before any other function who'll edit text like nl2br().

If you use nl2br() first, the htmlentities() function will change < br > to &lt;br&gt;.

Hi there,

after several and several tests, I figured out that dot:

- htmlentities() function remove characters like "à","è",etc when you specify a flag and a charset

- htmlentities() function DOES NOT remove characters like those above when you DO NOT specify anything

So, let's assume that..

<?php

$str = "Hèèèllooo";

$res_1 = htmlentities($str, ENT_QUOTES, "UTF-8");
$res_2 = htmlentities($str);

echo var_dump($res_1); // Result: string '' (length=0)
echo var_dump($res_2); // string 'H&egrave;&egrave;&egrave;llooo' (length=30)

?>

I used this for a textarea content for comments. Anyway, note that using the "$res_2" form the function will leave unconverted single/double quotes. At this point you should use str_replace() function to perform the characters but be careful because..

<?php

$str = "'Hèèèllooo'";

$res_2 = str_replace("'","&#039;",$str);
$res_2 = htmlentities($str);
echo var_dump($res_2); // string '&amp;#039;H&egrave;&egrave;&egrave;llooo&amp;#039;'

$res_3 = htmlentities($str);
$res_3 = str_replace("'","&#039;",$res_3);
echo var_dump($res_3); // string '&#039;H&egrave;&egrave;&egrave;llooo&#039;' --> Nice
?>

Hope it will helps you.

Regards,
W.D.

html entities does not encode all unicode characters. It encodes what it can [all of latin1], and the others slip through. &#1033; is the nasty I use. I have searched for a function which encodes everything, but in the end I wrote this. This is as simple as I can get it. Consult an ansii table to custom include/omit chars you want/don't. I'm sure it's not that fast.

// Unicode-proof htmlentities. 
// Returns 'normal' chars as chars and weirdos as numeric html entites.
function superentities( $str ){
    // get rid of existing entities else double-escape
    $str = html_entity_decode(stripslashes($str),ENT_QUOTES,'UTF-8'); 
    $ar = preg_split('/(?<!^)(?!$)/u', $str );  // return array of every multi-byte character
    foreach ($ar as $c){
        $o = ord($c);
        if ( (strlen($c) > 1) || /* multi-byte [unicode] */
            ($o <32 || $o > 126) || /* <- control / latin weirdos -> */
            ($o >33 && $o < 40) ||/* quotes + ambersand */
            ($o >59 && $o < 63) /* html */
        ) {
            // convert to numeric entity
            $c = mb_encode_numericentity($c,array (0x0, 0xffff, 0, 0xffff), 'UTF-8');
        }
        $str2 .= $c;
    }
    return $str2;

A useful little function to convert the symbols in the different inputs.
<?php
function ConvertSimbols($var, $ConvertQuotes = 0) {
if ($ConvertQuotes > 0) {
$var = htmlentities($var, ENT_NOQUOTES, 'UTF-8');
$var = str_replace('\"', '', $var);
$var = str_replace("\'", '', $var);
} else {
$var = htmlentities($var, ENT_QUOTES, 'UTF-8');
}
return $var;
}
?>

Usage with quotes for example message:

$message = ConvertSimbols($message);

Usage without quotes for example link:

$link = ConvertSimbols($link, 1);

Note that as of 5.2.5 it appears that if the input string contains a character that is not valid for the output encoding you've specified, then this function returns null.

You might expect it to just strip the invalid char, but it doesn't.

You can strip the chars yourself like so:

iconv('utf-8','utf-8',$str);

You can combine that with htmlentities also:

$str = htmlentities(iconv('UTF-8', 'UTF-8//IGNORE', $str, ENT_QUOTES, 'UTF-8');

Should give you a string with htmlentities encoded to utf-8, and any unsupported chars stripped.

This fuction is particularly useful against XSS (cross-site-scripting-). XSS makes use of holes in code, whether it be in Javascript or PHP. XSS often, if not always, uses HTML entities to do its evil deeds, so this function in co-operation with your scripts (particularly search or submitting scripts) is a very useful tool in combatting "H4X0rz".

I'm glad 5.4 has xml support, but many of us are working with older installations, some of us still have to use PHP4. If you're like me you've been frustrated with trying to use htmlentites/htmlspecial chars with xml output. I was hoping to find an option to force numeric encoding, lacking that, I have written my own xmlencode function, which I now offer:



usage: 



$string xmlencode( $string )



it will use htmlspecialchars for the valid xml entities amp, quote, lt, gt, (apos) and return the numeric entity for all other non alpha-numeric characters.



-------------------------------------------



<?php 

if( !function_exists( 'xmlentities' ) ) {

    function xmlentities( $string ) {

        $not_in_list = "A-Z0-9a-z\s_-";

        return preg_replace_callback( "/[^{$not_in_list}]/" , 'get_xml_entity_at_index_0' , $string );

    }

    function get_xml_entity_at_index_0( $CHAR ) {

        if( !is_string( $CHAR[0] ) || ( strlen( $CHAR[0] ) > 1 ) ) {

            die( "function: 'get_xml_entity_at_index_0' requires data type: 'char' (single character). '{$CHAR[0]}' does not match this type." );

        }

        switch( $CHAR[0] ) {

            case "'":    case '"':    case '&':    case '<':    case '>':

                return htmlspecialchars( $CHAR[0], ENT_QUOTES );    break;

            default:

                return numeric_entity_4_char($CHAR[0]);                break;

        }

There is a feature when writing to XML using an AJAX call to PHP that rarely is mentioned. I struggled for many hours using htmlentities() because what was getting written to my XML document was not as expected. I naturally assumed that I should be converting my strings before writing them to XML to adhere to XML rules on illegal characters. To my surprise, when converting with htmlentities() or htmlspecialchars() and then writing to an XML file, the resulting ampersands get converted afterwards! Consider the following example:

<?php
$str = "<b>I am cool</b>" ;
$str = htmlentities($str) ;
?>

When you append $str to an XML element and save() the document, you would expect the XML document's source code to look something like this:

<ele>&lt;b&gt;I am cool&lt;/b&gt;</ele>

But that is not what happens. The resulting ampersands get converted by PHP automatically to &amp; and your source code ends up looking like this:

<ele>&amp;lt;b&amp;gt;I am cool&amp;lt;/b&amp;gt;</ele>

As you can see, this creates problems when trying to output the XML data back to HTML. It is important to remember that when writing to XML this way, special characters like ">" and "<"; PHP converts them automatically and there becomes no need to use htmlentities() in certain cases. I assume this feature is in place to aid with passing data through header queries, to avoid reserved characters conflicting with others in a header query (e.g. & or =). Now I understand this may not be the case with older versions of PHP and that this might be a feature of my version (PHP version 5.6.32). With older versions, I assume using htmlentities() or htmlspecialchars() is a must, as stated with previous notes here. Also I use the charset UTF-8 in my HTML and XML and am not sure if this also effects the results I get.

Anyway, I struggled for many hours with using htmlentities() to convert strings for XML writing and saving, when all I had to do was simply not use the function and let PHP convert my strings for me. I hope this helps because I would think I am not the only one who has struggled with this situation.

I use this function to encode all the xml entities and also all the &something; that are not defined in xml like &trade;
You can also decode what you encode with my decode function.
My function works a little like the htmlentities.
You can also add other string to the array if you want to exclude them from the encoding.

<?php
function xml_entity_decode($text, $charset = 'Windows-1252'){
    // Double decode, so if the value was &amp;trade; it will become Trademark
    $text = html_entity_decode($text, ENT_COMPAT, $charset);
    $text = html_entity_decode($text, ENT_COMPAT, $charset);
    return $text;
}

function xml_entities($text, $charset = 'Windows-1252'){
     // Debug and Test
    // $text = "test &amp; &trade; &amp;trade; abc &reg; &amp;reg; &#45;";
    
    // First we encode html characters that are also invalid in xml
    $text = htmlentities($text, ENT_COMPAT, $charset, false);
    
    // XML character entity array from Wiki
    // Note: &apos; is useless in UTF-8 or in UTF-16
    $arr_xml_special_char = array("&quot;","&amp;","&apos;","&lt;","&gt;");
    
    // Building the regex string to exclude all strings with xml special char
    $arr_xml_special_char_regex = "(?";
    foreach($arr_xml_special_char as $key => $value){
        $arr_xml_special_char_regex .= "(?!$value)";
    }
    $arr_xml_special_char_regex .= ")";
    
    // Scan the array for &something_not_xml; syntax
    $pattern = "/$arr_xml_special_char_regex&([a-zA-Z0-9]+;)/";
    
    // Replace the &something_not_xml; with &amp;something_not_xml;
    $replacement = '&amp;${1}';
    return preg_replace($pattern, $replacement, $text);
}
?>

Trouble when using files with different charset?



htmlentities and html_entity_decode can be used to translate between charset!

A pointer to http://www.php.net/manual/en/function.mb-convert-encoding.php if your intention is to translate *all* characters in a charset to their corresponding HTML entities, not just named characters. Non-named characters will be replaced with HTML numeric encoding. eg:

$text = mb_convert_encoding($text, 'HTML-ENTITIES', "UTF-8");
