note 109698 added to control-structures.foreach

References created by foreach hang around past their best-used-by date. For example, the following: <?php $a = array('abe','ben','cam'); foreach ($a as $k=>&$n) $n = strtoupper($n); foreach ($a as $k=>$n) // notice NO reference here! echo "$n\n"; print_r($a); ?> will result in: ABE BEN BEN Array ( [0] => ABE [1] => BEN [2] => BEN ) ---- Server IP: 69.147.83.197 Probable Submitter: 74.195.32.53 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/109698 Del: integrated -- https://master.php.net/note/delete/109698/integrated Del: useless -- https://master.php.net/note/delete/109698/useless Del: bad code -- https://master.php.net/note/delete/109698/bad+code Del: spam -- https://master.php.net/note/delete/109698/spam Del: non-english -- https://master.php.net/note/delete/109698/non-english Del: in docs -- https://master.php.net/note/delete/109698/in+docs Del: other reasons-- https://master.php.net/note/delete/109698 Reject -- https://master.php.net/note/reject/109698 Search -- https://master.php.net/manage/user-notes.php
