trigger_error -- Generates a user-level error/warning/notice message
Description
void trigger_error (string error_msg [, int error_type])
Used to trigger a user error condition, it can be used by in conjunction 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:
if (assert ($divisor == 0))
trigger_error ("Cannot divide by zero", E_USER_ERROR);
