Oops, I didn't read your question too well. My answer makes no sense, sorry.

It's in $getID[1];, not $getID[2];. In PHP array's are 0-based, i.e., the first part is in $getID[0]; and the second part is in $getID[1];.

In cases like this it's always a good idea to do a var_dump($getID); to see what's going on.

Also... i wouldnt do it this way unless you -know- that the URL will only ever contain one variable.

For example; if someone sent this as your string:

"profile.php?userId=55&moo=cow"

Then your script will tell you that the value of userId is "55&moo=cow"

For this purpose I'd suggest using some more elegant solutions:

1. parse_url() to get the query part.
2. parse_str() to get the userId. This way your code is future-proof in case you add more parameters in the future.
