simple php redirection help

[batfink]

hey guys, how would i redirect to wap if the user is using a phone, and web if on a pc? i think its something to do with this? could anyone shed some light on this please?

if wml/wap

<?
header("location: /wap/");
?> 

if html/web

<?
header("location: /web/");
?> 

[batfink]

<?

header("HTTP/1.1");
header("Location: /web/");

header("vnd.wap.wml");
header("Location: /wap/");

?>

something like that? but i'm sure there meant to be an IF, ElSE statement there? :queasy:
