Custom errors for missing includes

[Anon]

Hi,

I noticed that some sites have a custom error msg when an include file is not found, how do they do that?

I don't mean a customised 404.

All I want is that when an include is not found or my script won't connect to the database, the error shown won't contain the absolute path of the file or database. Instead it should just say "Error (filename/databse) not found."

mysql_connect("","","") or die("Your message here");
