Notice: Undefined index: msg in C:\wamp\www\index.php on line 54

 

LINE 54:

Why? I just moved to my localhost, these error's never popped up on my hosting ?

Because your localhost has error_reporting set to E_STRICT whereas your hosting is probably set to everything except notices. It's a very low level error, it means you are trying to access the item 'msg' in the $_GET array, but there isn't one. You should be doing...

 

if(isset($_GET['msg'])) {
   // do something
} else {
   // do something else
}

Wat the hell does isset do?

Check the manual, isset. Simply put it allows you to check if a variable is..well set without throwing a notice if it isn't.

isset() returns true if the value you're giving it actually exists. If the value doesn't exist, it returns false.

Why php add these values? just use  = true on the $_GET instead of making it all complicated like this? im out

Because if you want to store FALSE in a variable, thats not the same as NULL, ie not having a value.

Notices aren't affected by E_STRICT, but E_NOTICE.

Oops, quite right, I meant E_ALL.
