SYNOPSIS

array_get($v, $keys)

DESCRIPTION

array_get returns the value in the multidimensional array $v designated by the sequence of keys specified by $keys.

If $keys is not an array or is empty, array_get returns false.

If one of the keys does not exist, or if an intermediate value is not an array, array_get returns false.

EXAMPLE

php > require 'library/dump.php';
php > require 'library/arrayget.php';
php > $arr=array('user' => array('name' => 'izend', 'mail' => 'webmaster@izend.org'));
php > dump(array_get($arr, array('user', 'mail')));
string(19) "webmaster@izend.org"

  2.     if (!is_array($keys) || empty($keys))
  3.         return false;
