Description
void
trigger_error ( string error_msg [, int error_type])

with the built-in error handler, or with a user defined function that has
been set as the new error handler
(set_error_handler()). It only works with the E_USER
family of constants, and will default to E_USER_NOTICE.
This function is useful when
you need to generate a particular response to an exception at runtime.
For example:
