parse_ini_string

(PHP 5 >= 5.3.0, PHP 7, PHP 8)

parse_ini_stringParse a configuration string

Опис

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.

Параметри

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.

Починаючи з PHP 5.6.1, можна визначати, як INI_SCANNER_TYPED. У цьому режимі логічні, нульові та цілочисельні типи збережуться за можливості. Рядки "true", "on" та "yes" перетворяться на true. Відповідно, "false", "off", "no" та "none" — на false. "null" перетвориться на null. Також, усі числові рядки перетворяться в цілі числа за можливості.

Значення, що повертаються

The settings are returned as an associative array on success, and false on failure.

Примітки

Зауваження: There are reserved words which must not be used as keys for ini files. These include: null, yes, no, true, false, on, off, none. Values null, off, no and false result in "", and values on, yes and true result in "1", unless INI_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] == "[" &amp;&amp; $endIdx = strpos($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(
$matches) &amp;&amp; isset($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(
$matches[1]) &amp;&amp; !empty($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.
