PHP equivalent of some JS-functions 1

[aspx]

Hi!
I collect information about users visiting my web-site with JavaScript+PHP, but I'd like to use PHP only.
Are there any equivalents in PHP of the following JS-functions:
1. Screen.width, Screen.height;
2. Screen.colordepth;
3. Document.referer;
4. Document.url.

Thanx in advance for any help!

There are no equivalents for 1 or 2. Those can only be gained using client-side scripting -- PHP runs on the server.

$_SERVER['HTTP_REFERER'] holds the URL of the page which sent the browser to the current page. This is only available if the browser has been configured to report that information to the server.

There are a couple of ways to get the current URL, depending on exactly what you want. I refer you to the PHP online documentation on $_SERVER (

http://www.php.net/manual/en/reserved.variables.php#reserved.variables.server)
