How do you use PHP to get the address of the current file?

Many ways, my friend, though it rather depends what you mean by 'address'. There's plenty of inbuilt variables you may wish to inspect:

$_SERVER['PHP_SELF'];
$_SERVER['PATH_TRANSLATED'];
$_SERVER['REQUEST_URI']; 

here's the relevant manpage

http://uk.php.net/reserved.variables

Okay, is there one that gives the document root - not $_SERVER["DOCUMENT_ROOT"] - without the script name?

getcwd() doesn't do that?

Is there any way to get the current URL?

I think it's $_SERVER["SCRIPT_NAME"].

[shimon]

yeah thats

$_SERVER['REQUEST_URI']; 

i think i mentioned that

What I want to do is set a variable as the url of the current page, then carry that value from one page to another and make a link to that varible by using:

print("<a href='$theurl'>Some text</a>");

Kind of, but not exactly what I was looking for. Some manipulation, but I guess that's one way you could do it.

How do I do this? I am developing a comment script for my site, and this is the last thing I need, so I really need to know!

You didn't quote anyone, but if you were talkin' to me, that variable changes depending on the page requested - my purposes would need something that never changes.

Well if you only need it once, then you could use $_GET variables - might be easier.

Ok, so is that something like this?
The main page(which will go to the next page when the form is submitted):

$theurl = 
$_SERVER['REQUEST_URI']; 

The page I have the link on:

$theurl = $_GET['theurl'];
print("<a href='$theurl'>Some Text</a> 

Or wait a minute. Since I'm using a form on the first page, would it be better just to store the url in a hidden input element, and use $_REQUEST['hiddenelement'] ?

You didn't quote anyone

Hmm now I understand that post count

But, no - I was taking to the guy who originally asked the question. The idea of the 'address' was vague and so I made a couple of suggestions and then pointed him towards the manual. I'm not sure where sessions come into it, unless you pass session IDs through the query string...and I'm pretty sure you wouldn't do that
