note 71854 added to control-structures.foreach

"As of PHP 5, you can easily modify array's elements by preceding $value with &. This will assign reference instead of copying the value." There are cases where array_walk or array_map are inadequate (conditional required) or you're just too lazy to write a function and pass values to it for use with array_map... My solution to foreach for php 4 and 5 to modify values of an array directly: <?php $testarr = array("a" => 1, "b" => 2, "c" => 3, "d" => 4); $testarr_keys = array_keys($testarr); $testarr_values = array_values($testarr); for ($i = 0; $i <= count($testarr) - 1; $i++) { $testarr[$testarr_keys[$i]] = $testarr_values[$i] * 2; } print_r($testarr); ?> ---- Server IP: 216.235.15.211 Probable Submitter: 142.166.242.46 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/71854 Del: integrated -- https://master.php.net/note/delete/71854/integrated Del: useless -- https://master.php.net/note/delete/71854/useless Del: bad code -- https://master.php.net/note/delete/71854/bad+code Del: spam -- https://master.php.net/note/delete/71854/spam Del: non-english -- https://master.php.net/note/delete/71854/non-english Del: in docs -- https://master.php.net/note/delete/71854/in+docs Del: other reasons-- https://master.php.net/note/delete/71854 Reject -- https://master.php.net/note/reject/71854 Search -- https://master.php.net/manage/user-notes.php
