Please do a search on the forum. This is asked very often.

No. You cannot just get a javascript var ina PhP script. You need to poass it through an url, or through a POST. Java runs on the clients PC, whereas PhP runs on the server.

You can echo the value of a PhP variable into the outputted javascript though.

if you want to make a javascript variable from php it would be something like;

<script language="javascript">

var foo = <? echo $bar; ?>;

</script>

the other way around is a bit trickier, and will require javascript to send the variable back to the server.

php runs on the server, javascript runs on the client.

The answer to this depends. If you are trying to process something after the user has already recieved the page, you can't. PHP is server side (code runs before the user gets the page), and JavaScript is client side (code runs after the user gets the page). So you can't make JavaScript interact with PHP without making another call to the server; however, if you want to pass the javascript variable to the server, you can do that using the url, such as

<script language = "JavaScript 1.0">
var someVar = "SomeValue";

document.write("<a href=http://someserver.com/page.php?page=" . someVar . ">Click Here</a>");

Or something similar (my JavaScripting is a little rusty, so I am not sure that it would look exactly like that, but you should know what I mean
