note 54329 added to function.empty

I needed to know if the variable was empty, but allow for it to be zero, so I created this function. I post it here in case anybody else needs to do that (it's not hard to make, but why reinvent the wheel...) <?php function is_extant($var) { if (isset($var)) { if ( empty($var) && ($var !== 0) && ($var !== '0') ) return FALSE; else return TRUE; } else return FALSE; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.empty.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+54329 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+54329&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+54329&report=yes Search -- http://master.php.net/manage/user-notes.php
