(PHP 5 >= 5.3.0, PHP 7, PHP 8)
parse_ini_string — Parse a configuration string
$ini_string
, bool $process_sections
= false
, int $scanner_mode
= INI_SCANNER_NORMAL
): array |false
parse_ini_string() returns the settings in string
ini_string
in an associative array.
The structure of the ini string is the same as the php.ini's.
ini_string
The contents of the ini file being parsed.
process_sections
By setting the process_sections
parameter to true
, you get a multidimensional array, with
the section names and settings included. The default
for process_sections
is false
scanner_mode
Can either be INI_SCANNER_NORMAL
(default) or
INI_SCANNER_RAW
. If INI_SCANNER_RAW
is supplied, then option values will not be parsed.
As of PHP 5.6.1 can also be specified as INI_SCANNER_TYPED
.
In this mode boolean, null and integer types are preserved when possible.
String values "true"
, "on"
and "yes"
are converted to true
. "false"
, "off"
, "no"
and "none"
are considered false
. "null"
is converted to null
in typed mode. Also, all numeric strings are converted to integer type if it is possible.
Note: There are reserved words which must not be used as keys for ini files. These include:
null
,yes
,no
,true
,false
,on
,off
,none
. Valuesnull
,off
,no
andfalse
result in""
, and valueson
,yes
andtrue
result in"1"
, unlessINI_SCANNER_TYPED
mode is used. Characters?{}|&~![()^"
must not be used anywhere in the key and have a special meaning in the value.
parse_ini_string_m is analog for a parse_ini_string function.
had to code this function due to the lack of a php 5.3 on some hosting.
parse_ini_string_m:
- ignores commented lines that start with ";" or "#"
- ignores broken lines that do not have "="
- supports array values and array value keys
<?php
function parse_ini_string_m($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
)
)
)
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 );
}
}
?>
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',
),
)

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.
