note 79261 added to control-structures.foreach

just discovered a possibility using foreach for iterating ob the original array instead of making a copy: function &wrap(&$a) { return $a; } $myArray = array(1, 2, 3); foreach (test($myArrav) as $myValue) { echo $myValue ." "; // testing the operation on reference by changing $myArray if ($myValue == 3) $myArray []= 4; } prints out: 1 2 3 4 ---- Server IP: 69.147.83.197 Probable Submitter: 87.170.164.233 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/79261 Del: integrated -- https://master.php.net/note/delete/79261/integrated Del: useless -- https://master.php.net/note/delete/79261/useless Del: bad code -- https://master.php.net/note/delete/79261/bad+code Del: spam -- https://master.php.net/note/delete/79261/spam Del: non-english -- https://master.php.net/note/delete/79261/non-english Del: in docs -- https://master.php.net/note/delete/79261/in+docs Del: other reasons-- https://master.php.net/note/delete/79261 Reject -- https://master.php.net/note/reject/79261 Search -- https://master.php.net/manage/user-notes.php
