ini_get_all

(PHP 4 >= 4.2.0, PHP 5)

ini_get_allGets all configuration options

Description

array ini_get_all ([ string $extension [, bool $details = true ]] )

Returns all the registered configuration options.

Parameters

extension

An optional extension name. If set, the function return only options specific for that extension.

details

Retrieve details settings or only the current value for each setting. Default is TRUE (retrieve details).

Return Values

Returns an associative array with directive name as the array key.

When details is TRUE (default) the array will contain global_value (set in php.ini), local_value (perhaps set with ini_set() or .htaccess), and access (the access level).

When details is FALSE the value will be the current value of the option.

See the manual section for information on what access levels mean.

Note:

It's possible for a directive to have multiple access levels, which is why access shows the appropriate bitmask values.

Examples

Example #1 ini_get_all() examples

<?php
print_r
(ini_get_all("pcre"));
print_r(ini_get_all());
?>

The above example will output something similar to:

Array
(
    [pcre.backtrack_limit] => Array
        (
            [global_value] => 100000
            [local_value] => 100000
            [access] => 7
        )

    [pcre.recursion_limit] => Array
        (
            [global_value] => 100000
            [local_value] => 100000
            [access] => 7
        )

)
Array
(
    [allow_call_time_pass_reference] => Array
        (
            [global_value] => 0
            [local_value] => 0
            [access] => 6
        )

    [allow_url_fopen] => Array
        (
            [global_value] => 1
            [local_value] => 1
            [access] => 4
        )

    ...

)

<?php
print_r
(ini_get_all("pcre"false)); // Added in PHP 5.3.0
print_r(ini_get_all(nullfalse)); // Added in PHP 5.3.0
?>

The above example will output something similar to:

Array
(
    [pcre.backtrack_limit] => 100000
    [pcre.recursion_limit] => 100000
)
Array
(
    [allow_call_time_pass_reference] => 0
    [allow_url_fopen] => 1
    ...

I guess the third entry is the required access level (to change this variable at runtime):

Constant           Value      Meaning
PHP_INI_USER      1          Entry can be set in user scripts
PHP_INI_PERDIR    2          Entry can be set in php.ini, .htaccess or httpd.conf 
PHP_INI_SYSTEM    4          Entry can be set in php.ini or httpd.conf 
PHP_INI_ALL       7          Entry can be set anywhere

Since a certain PHP version (I think it's 5.2.5) it is no longer possible to override INI entrys set with php_admin_* in httpd.conf. The access level will be set to 4 (PHP_INI_SYSTEM), which is also returned by this function.

The constants mentioned below are available in PHP, but without the prefix (e.g. INI_USER, INI_PERDIR).
