I must confess, that "sedativchunk at gmail dot com" in his comment at 02-Feb-2009 a bit wrong. Let's take simple example $a=0; switch($a) { case ($a < 100):echo 1;break; case ($a > 100):echo 2;break; } this will output 2 (TWO!). Seems strange? Nope at all. Switch is NOT simular to if($a<100) echo 1; elseif($a>100) echo 2; It's simular to if($a==($a<100)) echo 1; else ($a==($a>100)) echo 2; becase it's COMPRASSION to VALUE in switch. switch($bac) case $b*10 will compare $bac to $b*10 if you wanna use switch such way, use switch(true) { case ($a < 100):echo 1;break; case ($a > 100):echo 2;break; } because (true==($a<100)) is simular to $a<100 /edogs ---- Server IP: 78.41.104.32 Probable Submitter: 89.112.26.63 ---- Manual Page -- http://www.php.net/manual/en/control-structures.switch.php Edit -- https://master.php.net/note/edit/88770 Del: integrated -- https://master.php.net/note/delete/88770/integrated Del: useless -- https://master.php.net/note/delete/88770/useless Del: bad code -- https://master.php.net/note/delete/88770/bad+code Del: spam -- https://master.php.net/note/delete/88770/spam Del: non-english -- https://master.php.net/note/delete/88770/non-english Del: in docs -- https://master.php.net/note/delete/88770/in+docs Del: other reasons-- https://master.php.net/note/delete/88770 Reject -- https://master.php.net/note/reject/88770 Search -- https://master.php.net/manage/user-notes.php
