parse_ini_string

(PHP 5 >= 5.3.0)

parse_ini_string — Parse a configuration string

说明

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.

参数

ini

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.

返回值

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

注释

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 ?{}|&~![()^" must not be used anywhere in the key and have a special meaning in the value.

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 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;
    }
}
?>

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!
