[PHP] "Use of undefined constant" error
Hello,
I've got a strange pb. Here's my code
if(isset($_GET[id])){
do something...
else
do something else
}
?>
When I call myfile.php I've got the "somthing else" with no error.
When I call myfile.php?id=1 I've got the "something" but with an error
message "Notice: Use of undefined constant id - assumed 'id' in ..."
Please help

Hi,
> "Notice: Use of undefined constant id - assumed 'id' in ..."
Try changing this:
> if(isset($_GET[id])){
to this:
if(isset($_GET['id'])) {
note quotes
PHP thinks you're trying to use a constant called "id", which you haven't
defined - hence the "undefined constant" error ;-)
Note how the message says "assumed 'id'", which is what you should change it
to - this shouldn't stop your script from running, as the parser can work
out what you meant, but your error reporting is set sufficiently high that
PHP lets you know about it.
Cheers
Jon

Re: [PHP] "Use of undefined constant" error
you've got error reporting set pretty high to get that.
The correct way to reference an array element in this case
is $_GET["id"], if you do $_GET[id] you are telling PHP
to look for a constant called id. If it doesn't find one then
it assumes you meant "id" onstead of id and proceeds
accordingly. Thats why you can get away with not using the
quote marks (as long as there's no white space in the string).
On a live site (and, I'd have thought, most default set-ups)
you'd expect error reporting to be set all off and you'd
never see the message.
