note 115725 added to function.array-diff-key

Here's a simple function that returns true if all keys in the first array are found in the second array, and false if they aren't. function same_keys ($a1, $a2) { $same = false; if (!array_diff_key($a1, $a2)) { $same = true; foreach ($a1 as $k => $v) { if (is_array($v) && !same_keys($v, $a2[$k])) { $same = false; break; } } } return $same; } To check if two arrays have the same structure, ignoring values, execute the function twice, the second time with the arguments reversed. ---- Server IP: 216.194.115.244 Probable Submitter: 64.175.42.200 ---- Manual Page -- http://php.net/manual/en/function.array-diff-key.php Edit -- https://master.php.net/note/edit/115725 Del: integrated -- https://master.php.net/note/delete/115725/integrated Del: useless -- https://master.php.net/note/delete/115725/useless Del: bad code -- https://master.php.net/note/delete/115725/bad+code Del: spam -- https://master.php.net/note/delete/115725/spam Del: non-english -- https://master.php.net/note/delete/115725/non-english Del: in docs -- https://master.php.net/note/delete/115725/in+docs Del: other reasons-- https://master.php.net/note/delete/115725 Reject -- https://master.php.net/note/reject/115725 Search -- https://master.php.net/manage/user-notes.php
