_wp_array_get() │ WP 5.6.0

Accesses an array in depth based on a path of keys.

It is the PHP equivalent of JavaScript's lodash.get() and mirroring it may help other components retain some symmetry between client and server implementations.

Example usage:

$array = array(
	'a' => array(
		'b' => array(
			'c' => 1,
		),
	),
);
_wp_array_get( $array, array( 'a', 'b', 'c' ) );

Хуков нет.
