note 68746 added to control-structures.foreach

PHP arrays are really handy, but because foreach loops through array cells in order of CREATION, rather than in index order you cannot easily use them to implement priority queues. For example: <?php $priority_queue[1024] = 'sam'; $priority_queue[389] = 'sally'; $priority_queue[97] = 'tod'; $priority_queue[783] = 'mary'; foreach($priority_queue as $name) { echo "hello $name !\n"; } ?> Will NOT produce: hello tod ! hello sally ! hello mary ! hello sam ! as you may wish. ---- Server IP: 203.202.10.60 Probable Submitter: 130.130.37.6 (proxied: 130.130.109.88) ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/control-structures.foreach.php Edit -- https://master.php.net/note/edit/68746 Del: integrated -- https://master.php.net/note/delete/68746/integrated Del: useless -- https://master.php.net/note/delete/68746/useless Del: bad code -- https://master.php.net/note/delete/68746/bad+code Del: spam -- https://master.php.net/note/delete/68746/spam Del: non-english -- https://master.php.net/note/delete/68746/non-english Del: in docs -- https://master.php.net/note/delete/68746/in+docs Del: other reasons-- https://master.php.net/note/delete/68746 Reject -- https://master.php.net/note/reject/68746 Search -- https://master.php.net/manage/user-notes.php
