Catch all errors

Hi, I would like to catch errors in PHP/MySQL and display a generic error message of some sort rather than just 'undefined' or whatever else it may be.

Can you advise how to correctly do this?

I don't have time at the moment but the error message are saved to a text files in the same directory as the offending php file as they occur.

Edit:

Here is a link that might help:

http://www.w3schools.com/php/php_exception.asp

Also try Googling "Catch php errors" and see what useful links come up.

Hi thanks for the help, I use W3schools alot, and of course I search for the terms often - I just thought I'd ask here to find out what the professionals do rather than sift through various websites which don't teach the right/most uptodate method.
