how to get the url on the browse

[dzren]

Hi , everyone.
I have this problem for a long time.
How to get the url on the browser in php?
I know in javascript can work in this way:

<script>
<!--
var url;
url=this.location.href.toLowerCase();
//-->
</script>

But how to do it in php?
Thanks.

I'm afraid you can't do client operations using only PHP.
You can use your Javascript code in a PHP template by simply using echo or print, or by closing <? ?> signs.

You misunderstood,but thank you all the same.

My problem is I need the url on browser in my php code.
I know javascript can get it, I want to know php can or not.
Or is there any way to get the variable in javacript?
Now I redirect the page to add the url variable,like:

<script>
var url=this.location.href.toLowerCase();
document.location.href='index.php?url='+url;
</script>

Then I analyse $url.
Is there any way to solve it in one file?

The Manual may well have something in its section on predefined variables.

If I type "http://[e-mail]" in the location of a browser,
which means a user named "me" to visit the site "http://phpbuilder.com".That is OK.But in php,I use

$url="http://".$SERVER_NAME.$PHP_SELF;

only get "http://phpbuilder.com",not including "me@".
But my real purpose is getting "me".
How can i do?
