note 58054 added to function.isset

i worked on a calculator so the user-input could be zero -> couldn´t use !empty() cause it returns FALSE on those. but i was also too lazy to write: if(isset($_GET['var']) && $_GET['var']!='') so i wrote this function: function cuv($varname,$postget=1) { if($postget) { if(isset($_POST[$varname]) && $_POST[$varname]!='') return (bool) 1; else return (bool) 0; } else { if(isset($_GET[$varname]) && $_GET[$varname]!='') return (bool) 1; else return (bool) 0; } } so to check GET vars i only have to write: if(cuv($varname,0)) and for post vars only: if(cuv($varname)) ---- Manual Page -- http://www.php.net/manual/en/function.isset.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58054 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58054&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58054&report=yes Search -- http://master.php.net/manage/user-notes.php
