(PHP 4 >= 4.2.0, PHP 5, PHP 7)
ini_get_all — Gets all configuration options
ini_get_all ([ string $extension [, bool $details = true ]] ) : array
Returns all the registered configuration options.
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).
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
accessshows the appropriate bitmask values.
Note:
ini_get_all() ignores "array" ini options such as pdo.dsn.*.
