note 55571 added to function.key

A better key_in_array(): <?php function key_in_array($needle, $haystack) { return in_array($needle, array_flip($haystack)); } ?> (Note that even when you want to convert something to a boolean (if it isn't already), then !!$something is better than $something?true:false and much better than a long if construct with explicit returns, IMHO) ---- Manual Page -- http://www.php.net/manual/en/function.key.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55571 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55571&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55571&report=yes Search -- http://master.php.net/manage/user-notes.php
