Javascript variables..

[Theta]

In PHP is there a way to use document.write to set a variable in PHP.

As I am not too sure what order the scripts are run (I am assuming that PHP is executed on the server before JavaScript on the client, then again assumptions are mothers by themselfs). Please could I get some help with the following script:

<script LANGUAGE="JavaScript">
<!--
if (window.screen) {
document.write('screen.height: <?php $variable = ; ?>' + screen.height + " <?php print $variable ;?><BR>");
document.write('screen.width: ' + screen.width + "<BR>");
document.write('screen.availHeight: ' + screen.availHeight + "<BR>");
document.write('screen.availWidth: ' + screen.availWidth + "<BR>");
document.write('screen.colorDepth: ' + screen.colorDepth + "<BR>");
}
//-->
</script>

my problem comes with trying to set that variable without a page re-fresh using redirects... Of course if this is the only way then I'll have to populate a form and send over the values in a header using hidden fields filled out with the JavaScript data.

Muchos Thankos.

The browser will only display $variable if it has been set before outputting the html.

You cannot use the clientside document.write to set serverside variables. Not initially anyway.

Javascript can set cookies, then PHP can read them (after a new page request). Output buffering doesn't work in my tests.
