ini_get_all

(PHP 4 >= 4.2.0, PHP 5, PHP 7, PHP 8)

ini_get_all — Gets all configuration options

Beschreibung

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

Returns all the registered configuration options.

Parameter-Liste

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).

Rückgabewerte

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.

Hinweis:

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

Beispiele

Beispiel #1 ini_get_all() examples

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

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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
        )

    ...

)

Beispiel #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
?>

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

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

Anmerkungen

Hinweis:

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