I'm having trouble with the newest version of PHP (4.2.2).
For example in a page I'm using the following code:
if ($_GET['action'] == "logout") {
//do something
}
But I'm getting an error message that says:
...log_message reports: PHP Notice: Undefined index: action in....
Ealier (other versions of PHP) I have succesfully used the above code, but do
I now have to rewrite the code like this:
if (isset($_GET['action']) AND $_GET['action'] == "logout") {
//do something
}
Or am I totally wrong?
This was just one example when I'm getting the message "Undefined index" or "
Undefined variable" etc. A lot of code which has previously worked is now
giving me loads of headache since I have to rewrite everything.
Please, I need some help.
