parse_ini_file
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)
parse_ini_string — Parse a configuration string
Description
array parse_ini_string
( string
$ini
[, bool $process_sections = false
[, int $scanner_mode = INI_SCANNER_NORMAL
]] )
parse_ini_string() returns the settings in string
ini in an associative array.
The structure of the ini string is the same as the php.ini's.
Parameters
-
ini -
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.
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. Values null, no and false results in "", yes and true results in "1". Characters ?{}|&~

If your server has yet not been updated to PHP 5.2 (like mine), the following function can help you without having to use temporary paths.
I tried to make it the more similar possible to the PHP's behaviour, including dealing with errors or exceptions.
<?php
if(!function_exists('parse_ini_string')){
function parse_ini_string($str, $ProcessSections=false){
$lines = explode("\n", $str);
$return = Array();
$inSect = false;
foreach($lines as $line){
$line = trim($line);
if(!$line || $line[0] == "#" || $line[0] == ";")
continue;
if($line[0] == "[" && $endIdx = strpos($line, "]")){
$inSect = substr($line, 1, $endIdx-1);
continue;
}
if(!strpos($line, '=')) // (We don't use "=== false" because value 0 is not valid as well)
continue;
$tmp = explode("=", $line, 2);
if($ProcessSections && $inSect)
$return[$inSect][trim($tmp[0])] = ltrim($tmp[1]);
else
$return[trim($tmp[0])] = ltrim($tmp[1]);
}
return $return;
}
}
?>

Function parse_ini_file doesn't parse a remote ini file if allow_url_include is off. But if allow_url_fopen is on, you can use parse_ini_string to parse a remote ini file after read its contents.
<?php
/**
* Assume that; allow_url_include=0 and allow_url_fopen=1
* (default values in php.ini)
*/
$iniUrl = 'http://example.com/remote/config.ini';
/**
* Warning: parse_ini_file(): http:// wrapper is disabled in the server configuration by allow_url_include=0
*/
$config = parse_ini_file($iniUrl);
/**
* works fine
*/
$config = parse_ini_string(file_get_contents($iniUrl));

If you want to use something like this on a PHP version below that of PHP 5.3, you can emulate it roughly by doing something like this:
<?php
if(!function_exists('parse_ini_string'))
{
function parse_ini_string($ini, $process_sections = false, $scanner_mode = null)
{
# Generate a temporary file.
$tempname = tempnam('/tmp', 'ini');
$fp = fopen($tempname, 'w');
fwrite($fp, $ini);
$ini = parse_ini_file($tempname, !empty($process_sections));
fclose($fp);
@unlink($tempname);
return $ini;
}
}
?>
May not be the most efficient way (I suppose you could do some regex stuff instead...) but it certainly works!
