ini_get_all

Gets all configuration options

Description

arrayfalse ini_get_all(stringnull $extension = null, bool $details = true)

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), 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
        )

    ...

)

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.*.
