note 54290 added to control-structures.foreach

One notice that foreach has strange behaviour with copying array. It sometimes doubles one array item. For example: <?php $array = array( 0 => array("one" => "x", "two" => "y"), 1 => array("one" => "z", "two" => "a"), 2 => array("one" => "b", "two" => "c") ) foreach ($array as $item) { echo $item["one"]." - ".$item["two"]."<br />"; } /* x - y z - a z - a b - c */ This can be avoided with reference: foreach ($array as &$item) { echo $item["one"]." - ".$item["two"]."<br />"; } /* x - y z - a b - c */ ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54290 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54290&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54290&report=yes Search -- http://master.php.net/manage/user-notes.php
