Error Handling On Displays the following Errors

[holoc]

Kept on getting these errors when the Error Handling and E_STRICT | E_DEPRECATED errors:

Notice: Undefined index: s in C:\xampp\htdocs\irclogger\index.php on line 21

Notice: Undefined index: u in C:\xampp\htdocs\irclogger\index.php on line 28

Notice: Undefined variable: date in C:\xampp\htdocs\irclogger\index.php on line 62

Ended up deciding to just disable the error handling so I don't see the errors.
