Heh it's alright

btw &= is a valid operator. You use it to replace:
$a = $a & $b;
with $a &= $b;

=& isnt an operator, it's just a = followed by a &, you can write
$a = &$b;
and it will do the same thing

I Liked the tutorial
Got some questions - Let's say i use <a href='bla.bla?bla=blat'> , the item would belong to the get array ?
Can i refer to him as a $_GET['bla'] ? cause i used this only for values submited by froms until now ...

2nd question isn't really about tutorial, just wanted to ask what this line means :
$id = ( isset( $_GET['id'] ) ) ? intval( $_GET['id'] ) : 0;
i can understand $id = ( isset( $_GET['id'] ) ) , but what does the "?" mean? and what does the ": 0" means ?

Thanks ! good tut, helped me

heres a link to my tut on superglobals and variable scope and stuff - it answers your problem. It covers a wider scope of things then EvilGen's but his goes into more detail, but mine gets the basic point accross.

and about the $id = ( isset( $_GET['id'] ) ) ? intval( $_GET['id'] ) : 0;

it's only an if-else statement, it's the same as :

if( isset( $_GET['id'] ) )
{
$id = intval( $_GET['id'];
}
else
{
$id = 0;
}

it's way shorter
