How can I get the screen size of mobile devices when they hit my web server?

问题

I want to get the screen size of mobile devices when they hit a URL on my server.

O am already using echo$_SERVER['HTTP_USER_AGENT']. How can I get the screen size? Can it be done by using jQuery/JavaScript?

回答1:

do it in javascript then send it up to php:

<script language='JavaScript'>
function detect()
{
alert('Screen resolution is '+screen.width+'x'+screen.height+'.');
}
</script>

<a href='#' onclick='detect();return false;'>Detect Screen Resolution</a>
