You aren't getting the value to the PHP script... allow me to walk through
what is actually happening
$resolution = "<SCRIPT
LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>";
echo "--".$resolution."--";
You have just set a variable to "<SCRIPT
LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>" and then
echoed that string. so it looks like you have
--1024-- or whatever your resolution is. if you view source though you see
you really have
--<SCRIPT LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>--
and the client browser is just interpreting that JavaScript statement
if (($resolution*1) >= 1024) {
$resolution = "1024";
} else {
$resolution = "800";
}
echo "**".$resolution."**";
The reason this isn't acting the way you expect is because you AREN'T saying
if ((1024*1) >= 1024 {
You are actually saying
if ((<SCRIPT
LANGUAGE=\"JavaScript\">document.write(screen.width)</SCRIPT>*1) >= 1024) {
You are not actually passing anything from JavaScript to PHP... you are just
tricking yourself =)
