note 60738 added to function.setcookie

hello everybody,, i'm not much of an expert in PHP, but what do you guys think of this one: <?php // tell the script if $_GET is "out" then DELETE cookie if(isset($do) && $do == out){ setcookie('COOKIESNAME'); } // tell the script if $_GET is "in" then SET cookie if($_GET['do'] == "in"){ setcookie('COOKIESNAME','world',time()+3600); ECHO "HEY, WELCOME YOU ..IN.."; } if($_GET['do'] == "out"){ ECHO "THANKS, VISIT AGAIN SOMETIME"; } ?> Would it work to add and delete cookies ""SAFELY"" and easly? ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+60738 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+60738&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+60738&report=yes Search -- http://master.php.net/manage/user-notes.php
