note 119673 added to class.arrayobject

You can use the array functions on a object of a class that implements ArrayAccess using the __invoke magic method in this way: <?php class ArrayVar implements ArrayAccess { private $data = []; public function __invoke() { return $this->data; } } ?> Now you can use like this: <?php $arrayar = new ArrayVar(); $arrayar['one'] = 'primer'; $arrayar['two'] = 'segon'; $arrayar['three'] = 'tercer'; $keys = array_keys($arrayar()); var_dump($keys); // array (size=3) // 0 => string 'one' // 1 => string 'two' // 2 => string 'three' $diff = array_diff($arrayar(), [ 'two' => 'segon']); var_dump($diff); // array (size=2) // 'one' => string 'primer' // 'three' => string 'tercer' ?> ---- Server IP: 72.52.91.14 Probable Submitter: 185.38.128.95 ---- Manual Page -- http://php.net/manual/en/class.arrayobject.php Edit -- https://master.php.net/note/edit/119673 Del: integrated -- https://master.php.net/note/delete/119673/integrated Del: useless -- https://master.php.net/note/delete/119673/useless Del: bad code -- https://master.php.net/note/delete/119673/bad+code Del: spam -- https://master.php.net/note/delete/119673/spam Del: non-english -- https://master.php.net/note/delete/119673/non-english Del: in docs -- https://master.php.net/note/delete/119673/in+docs Del: other reasons-- https://master.php.net/note/delete/119673 Reject -- https://master.php.net/note/reject/119673 Search -- https://master.php.net/manage/user-notes.php
