parse_ini_string_m is analog for a parse_ini_string function.
had to code this function due to the lack of a php 5.3 on some hosting.
parse_ini_string_m:
- ignores commented lines that start with ";" or "#"
- ignores broken lines that do not have "="
- supports array values and array value keys
<?php
function parse_ini_string_m($str) {
if(empty($str)) return false;
$lines = explode("\n", $str);
$ret = Array();
$inside_section = false;
foreach($lines as $line) {
$line = trim($line);
if(!$line || $line[0] == "#" || $line[0] == ";") continue;
if($line[0] == "[" && $endIdx = strpos($line, "]")){
$inside_section = substr($line, 1, $endIdx-1);
continue;
}
if(!strpos($line, '=')) continue;
$tmp = explode("=", $line, 2);
if($inside_section) {
$key = rtrim($tmp[0]);
$value = ltrim($tmp[1]);
if(preg_match("/^\".*\"$/", $value) || preg_match("/^'.*'$/", $value)) {
$value = mb_substr($value, 1, mb_strlen($value) - 2);
}
$t = preg_match("^\[(.*?)\]^", $key, $matches);
if(!empty($matches) && isset($matches[0])) {
$arr_name = preg_replace('#\[(.*?)\]#is', '', $key);
if(!isset($ret[$inside_section][$arr_name]) || !is_array($ret[$inside_section][$arr_name])) {
$ret[$inside_section][$arr_name] = array();
}
if(isset($matches[1]) && !empty($matches[1])) {
$ret[$inside_section][$arr_name][$matches[1]] = $value;
} else {
$ret[$inside_section][$arr_name][] = $value;
}
} else {
$ret[$inside_section][trim($tmp[0])] = $value;
}
} else {
$ret[trim($tmp[0])] = ltrim($tmp[1]);
}
}
return $ret;
}
?>
example usage:
<?php
$ini = '
[simple]
val_one = "some value"
val_two = 567
[array]
val_arr[] = "arr_elem_one"
val_arr[] = "arr_elem_two"
val_arr[] = "arr_elem_three"
[array_keys]
val_arr_two[6] = "key_6"
val_arr_two[some_key] = "some_key_value"
';
$arr = parse_ini_string_m($ini);
?>
variable $arr output:
Array
(
[simple] => Array
(
[val_one] => some value
[val_two] => 567
)
[array] => Array
(
[val_arr] => Array
(
[0] => arr_elem_one
[1] => arr_elem_two
[2] => arr_elem_three
)
)
[array_keys] => Array
(
[val_arr_two] => Array
(
[6] => key_6
[some_key] => some_key_value
)
)
)
parse_ini_string
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
parse_ini_string — Parse a configuration string
Description
parse_ini_string(string
$ini_string, bool $process_sections = false, int $scanner_mode = INI_SCANNER_NORMAL): array|false
parse_ini_string() returns the settings in string
ini_string in an associative array.
The structure of the ini string is the same as the php.ini's.
Parameters
-
ini_string -
The contents of the ini file being parsed.
-
process_sections -
By setting the
process_sectionsparameter totrue, you get a multidimensional array, with the section names and settings included. The default forprocess_sectionsisfalse -
scanner_mode -
Can either be
INI_SCANNER_NORMAL(default) orINI_SCANNER_RAW. IfINI_SCANNER_RAWis supplied, then option values will not be parsed.As of PHP 5.6.1 can also be specified as
INI_SCANNER_TYPED. In this mode boolean, null and integer types are preserved when possible. String values"true","on"and"yes"are converted totrue."false","off","no"and"none"are consideredfalse."null"is converted tonullin typed mode. Also, all numeric strings are converted to integer type if it is possible.
Return Values
The settings are returned as an associative array on success,
and false on failure.
Notes
Note: There are reserved words which must not be used as keys for ini files. These include:
null,yes,no,true,false,on,off,none. Valuesnull,off,noandfalseresult in"", and valueson,yesandtrueresult in"1", unlessINI_SCANNER_TYPEDmode is used. Characters?{}|&~

Replacement for php_ini_string() for PHP pre 5.3 - uses php_ini_file() and streams
<?php
if ( !function_exists( 'parse_ini_string' ) ) {
function parse_ini_string( $string, $process_sections ) {
if ( !class_exists( 'parse_ini_filter' ) ) {
/* Define our filter class */
class parse_ini_filter extends php_user_filter {
static $buf = '';
function filter( $in, $out, &$consumed, $closing ) {
$bucket = stream_bucket_new( fopen('php://memory', 'wb'), self::$buf );
stream_bucket_append( $out, $bucket );
return PSFS_PASS_ON;
}
}
/* Register our filter with PHP */
stream_filter_register("parse_ini", "parse_ini_filter")
or return false;
}
parse_ini_filter::$buf = $string;
return parse_ini_file( "php://filter/read=parse_ini/resource=php://memory", $process_sections );
}
}
?>

Hi,
Up to PHP 8.3 (at least), it seems that INI_SCANNER_TYPED is ignored when trying to get values from constants.
For example :
<?php
// https://3v4l.org/qK5o8
const OK = true;
const KO = false;
const NIL = null;
$ini = <<<'INI'
a = TRUE
b = FALSE
c = null
d = 9223372036854775807
INI;
var_dump(parse_ini_string($ini, false, INI_SCANNER_NORMAL), parse_ini_string($ini, false, INI_SCANNER_TYPED));
$ini = <<<'INI'
a = OK
b = KO
c = NIL
d = PHP_INT_MAX
INI;
var_dump(parse_ini_string($ini, false, INI_SCANNER_NORMAL), parse_ini_string($ini, false, INI_SCANNER_TYPED));
?>
I thought it was worth mentioning.

With function parse_ini_stringM() below you can:
- fix unvalued fields ('key' (invalid) ==> 'key=' (OK) )
- fix unquotted values with equal sign '=' ('key=value_part1=value_part2' ==> 'key="value_part1=value_part2"')
- fix (solve) multidimensional arrays (makes 'key[key1][key2]=value' valid)
function parse_ini_stringM() on github https://gist.github.com/msegu/c43a871c5a874a1d9bff978b448a0aa4 (here is too long)
// Example:
$ini = '[a]
b
c=d
e=';
var_export(parse_ini_string($ini, TRUE)); /* array (
'a' =>
array (
'c' => 'd',
'e' => '',
),
)
*/
$ini .= '
f[g][2]=h
f[g][i]=j
f[g][][]=k
m=n=o';
var_export(parse_ini_string($ini, TRUE)); // false
var_export(parse_ini_stringM($ini, TRUE)); /* array (
'a' =>
array (
'b' => '',
'c' => 'd',
'e' => '',
'f' =>
array (
'g' =>
array (
2 => 'h',
'i' => 'j',
3 =>
array (
0 => 'k',
),
),
),
'm' => 'n=o',
),
)
*/
