parse_ini_string

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

parse_ini_string解析配置字符串

说明

parse_ini_string(string $ini_string, bool $process_sections = false, int $scanner_mode = INI_SCANNER_NORMAL): array|false

parse_ini_string() 返回 ini_string 字符串解析后的关联数组。

ini 字符串的格式参考 php.ini

参数

ini_string

ini 字符串内容。

process_sections

设置 process_sections 参数为 true,得到一个多维数组,包含名称和设置。process_sections 默认为 false

scanner_mode

可以是 INI_SCANNER_NORMAL (默认)或 INI_SCANNER_RAW。如果是 INI_SCANNER_RAW,那么选项值不会被解析。

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.

返回值

执行成功返回一个关联数组,返回 false 为失败。

注释

注意: 有些保留字不能作为 ini 文件中的键名,包括:nullyesnotruefalseonoffnone。除非使用 INI_SCANNER_TYPED 模式,否则 nulloffnofalse 的值等效于 ""onyestrue 的值等效于 "1"。字符 ?{}|&~![()^" 也不能用在键名的任何地方,而且这些字符在选项值中有着特殊的意义。

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',
  ),
)
*/
