note 95299 added to function.array-keys

Re: Sven (bitcetera.com) on 19-Dec-2005 02:43 Unfortunately all of those array functions are passed by reference, so you now get a "Strict Standards" warning for trying to modify the return value of reference-enabled functions. To fix this use non destructive methods like current() and array_reverse() to achieve the same effect: <?php $array = array('first'=>'111', 'second'=>'222', 'third'=>'333'); // get the first key: returns 'first' printf("First Key: %s\n", current(array_keys($array))); // get the last key: returns 'third' printf("Last Key: %s\n", current(array_reverse(array_keys($array)))); // get the first value: returns '111' printf("First Val: %d\n", current(array_values($array))); // get the last value: returns '333' printf("Last Val: %d\n", current(array_reverse(array_values($array)))); ?> Outputs: First Key: first Last Key: third First Val: 111 Last Val: 333 ---- Server IP: 69.147.83.197 Probable Submitter: 76.247.173.69 ---- Manual Page -- http://www.php.net/manual/en/function.array-keys.php Edit -- https://master.php.net/note/edit/95299 Del: integrated -- https://master.php.net/note/delete/95299/integrated Del: useless -- https://master.php.net/note/delete/95299/useless Del: bad code -- https://master.php.net/note/delete/95299/bad+code Del: spam -- https://master.php.net/note/delete/95299/spam Del: non-english -- https://master.php.net/note/delete/95299/non-english Del: in docs -- https://master.php.net/note/delete/95299/in+docs Del: other reasons-- https://master.php.net/note/delete/95299 Reject -- https://master.php.net/note/reject/95299 Search -- https://master.php.net/manage/user-notes.php
