weirdness with foreach()

[pelleas]

okay. so i've been using this dealy to get information out of teh query string. here's the code:

foreach($_GET as $key=>$val){
$$key = $val;
}

is cool and all, as it seems to be working just right...i can get the information out, and it automatically sets each key to it's correct variable. but for some reason i get this error message along with the output i'm hoping for:

Warning: Invalid argument supplied for foreach()
in /host/mysite/mypage.phpon line 30

anybody got any ideas as to why i'm getting this? everything seems to be in order, as i'm getting all the output i want. it's just that i'm getting this error message displayed too....

You're right; that loop does appear to be in order; $_GET does exist and it is an array (if only an empty one), so that wouldn't be a problem - and that's the only place where a problem might spring up, as far as I can see.

What you could instead , though, is replace the loop with [man]extract/man;. That would have the same result.

The problem is that at the moment $_GET is empty.
And, BTW, there's simplier way to accomplish your task:
[man]extract()[/man]
