[ciapug] File Upload

[Carl Olsen]

The following error types cannot be handled with a user defined function:
E_ERROR, E_PARSE, E_CORE_ERROR, E_CORE_WARNING, E_COMPILE_ERROR,
E_COMPILE_WARNING, and most of E_STRICT raised in the file where
set_error_handler() is called. 

If errors occur before the script is executed (e.g. on file uploads) the
custom error handler cannot be called since it is not registered at that
time.

You mean by calling something like this?
