PHP: ini_get

Description

function ini_get_all(?string $extension = null, bool $details = true): array|false

Returns all the registered configuration options.

Parameters

extension: An optional extension name. If not null or the string core, the function returns 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. Returns false and raises an E_WARNING level error if the extension doesn't exist.

When details is true (default) the array will contain global_value (set in php.ini), local_value (perhaps set with ini_set() or .htaccess), builtin_default_value (the built-in default value of the directive, or null if it has none, independent of values set in php.ini, on the command line, or at runtime), 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.

Changelog

Version	Description
8.6.0	The `builtin_default_value` element was added to the details array returned for each directive.

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
            [builtin_default_value] => 100000
            [access] => 7
        )

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

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

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

    ...

)

Example #2 Disabling details

<?php
print_r(ini_get_all("pcre", false)); // Added in PHP 5.3.0
print_r(ini_get_all(null, false)); // 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
    ...
)

Notes

Note:
ini_get_all() ignores "array" ini options such as pdo.dsn.*.
