note 97112 added to control-structures.switch

Apparently you need to be extra careful with "0" (zero) in your case statements when mixing int and string values: switch($key) { case 0: echo "only if I am zero";break; case 1: echo "I'm one";break; case "E1": echo "Why don't you output me?";break; default: echo "No value Found"; } Switch will be convinced that you mean "0" when you really mean "E1" unless you wrap it in quotes: switch($key) { case '0': echo "only if I am zero";break; case 1: echo "I'm one";break; case "E1":echo "Yay! I'm back!";break; default: echo "No value Found"; } Maybe this is what they mean by "loose comparison" with True, False operators? ---- Server IP: 208.69.120.55 Probable Submitter: 63.82.71.139 ---- Manual Page -- http://www.php.net/manual/en/control-structures.switch.php Edit -- https://master.php.net/note/edit/97112 Del: integrated -- https://master.php.net/note/delete/97112/integrated Del: useless -- https://master.php.net/note/delete/97112/useless Del: bad code -- https://master.php.net/note/delete/97112/bad+code Del: spam -- https://master.php.net/note/delete/97112/spam Del: non-english -- https://master.php.net/note/delete/97112/non-english Del: in docs -- https://master.php.net/note/delete/97112/in+docs Del: other reasons-- https://master.php.net/note/delete/97112 Reject -- https://master.php.net/note/reject/97112 Search -- https://master.php.net/manage/user-notes.php
