Spliting a page address

[mhodgson]

I'm sure this is a fairly 'simple' one but I've confused myself trying to do it.

If I have a page address

e.g. "subjects.php?namefirst=Fname&sel_year=Y5&sel_class=all"

 

can I then grab it and split it at the ? so that I can pass everything after the ?

 

'namefirst=Fname&sel_year=Y5&sel_class=all'

 

onto another page?

explode();

 

$url = $_SERVER['HTTP_HOST'];

$spliturl = explode("?", $url);

 

echo $spliturl[1];

 

That will contain everything after the ? in your full URL

Didn't work.

$url = $_SERVER['HTTP_HOST']; only gave the web server (localhost in my case).

 

However played around with the $_server[] bit

tried $_SERVER['PHP_SELF'] but that left out the stuff after the ?.

After a little searching found this

$_SERVER['REQUEST_URI'];

 

Added it into the code and it seems to give me what I want.

 

$url = $_SERVER['REQUEST_URI'];

$spliturl = explode("?", $url);

 

echo $spliturl[1];

 

Thanks for the help.
