Getting info from url

[Qwerdox]

How isit possible to get variables from the php files own url?

Ex.: http://www.mysite.com/phpfile.php?A=abc&D=def

i would like to get to get the variables
$A and $D in that file. And when A or D changes in the url it also changes the variables $a and $D..

Hope this isn't the lamest question....

Those are GET variables in the url. You can acces them using $GET['A'] and $GET['D']...

For example:
echo $_GET['A']
..would output 'abc'

Ok thanx,

and if I would like to use this variable more often in the file how should I use it?

For example:
$_GET['A'] is the variable?

Then another question...

for example:
file.php?A=H1

from this I would like to get 2 variables..
A could be H1 trought H5 or D1 trough D9

1. If its a H a variable (ex: $team) should be HS if its a D is should be DS.
2. Just the numbers in A as a variable? $nr = 1
