note 111808 added to control-structures.foreach

Note that if you pass some function that returns an array to iterate it, that function would call just once: <?php $i = 0; function arr() { global $i; $i++; return array('1', '2', '3', '4', $i); } foreach (arr() as $k => $v) echo '['. $k .'] = '. $v ."\n"; /* [0] = 1 [1] = 2 [2] = 3 [3] = 4 [4] = 1 but not [0] = 1 [1] = 2 [2] = 3 [3] = 4 [4] = 5 */ ?> ---- Server IP: 69.147.83.199 Probable Submitter: 213.151.8.2 ---- Manual Page -- http://php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/111808 Del: integrated -- https://master.php.net/note/delete/111808/integrated Del: useless -- https://master.php.net/note/delete/111808/useless Del: bad code -- https://master.php.net/note/delete/111808/bad+code Del: spam -- https://master.php.net/note/delete/111808/spam Del: non-english -- https://master.php.net/note/delete/111808/non-english Del: in docs -- https://master.php.net/note/delete/111808/in+docs Del: other reasons-- https://master.php.net/note/delete/111808 Reject -- https://master.php.net/note/reject/111808 Search -- https://master.php.net/manage/user-notes.php
