parse_ini_string
(PHP 5 >= 5.3.0, PHP 7, PHP 8)
parse_ini_string — 解析配置字符串
说明
$ini_string
, bool $process_sections
= false
, int $scanner_mode
= INI_SCANNER_NORMAL
): array|false
parse_ini_string() 返回 ini_string
字符串解析后的关联数组。
ini 字符串的格式参考 php.ini
参数
ini_string
-
ini 字符串内容。
process_sections
-
设置
process_sections
参数为true
,得到一个多维数组,包含名称和设置。process_sections
默认为false
。 scanner_mode
-
可以是
INI_SCANNER_NORMAL
(默认)或INI_SCANNER_RAW
。如果是INI_SCANNER_RAW
,那么选项值不会被解析。As of PHP 5.6.1 can also be specified as
INI_SCANNER_TYPED
. In this mode boolean, null and integer types are preserved when possible. String values"true"
,"on"
and"yes"
are converted totrue
."false"
,"off"
,"no"
and"none"
are consideredfalse
."null"
is converted tonull
in typed mode. Also, all numeric strings are converted to integer type if it is possible.
返回值
执行成功返回一个关联数组,返回 false
为失败。
注释
注意: 有些保留字不能作为 ini 文件中的键名,包括:
null
、yes
、no
、true
、false
、on
、off
、none
。除非使用INI_SCANNER_TYPED
模式,否则null
、off
、no
和false
的值等效于""
,on
、yes
和true
的值等效于"1"
。字符?{}|&~![()^"
也不能用在键名的任何地方,而且这些字符在选项值中有着特殊的意义。
用户贡献的备注 4 notes
parse_ini_string_m is analog for a parse_ini_string function.
had to code this function due to the lack of a php 5.3 on some hosting.
parse_ini_string_m:
- ignores commented lines that start with ";" or "#"
- ignores broken lines that do not have "="
- supports array values and array value keys
<?php
function parse_ini_string_m($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.
