## Definition and Usage

The trigger_error() function creates a user-defined error message.

The trigger_error() function is used to trigger an error message at a user-specified condition. It can be used with the built-in error handler, or with a user defined function set by the set_error_handler() function.
This function is useful when you need a user-defined message to a specified condition when running a script runtime.

This function returns FALSE if a non valid error type is specified, and TRUE otherwise.

## Syntax
