Описание

bool 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()).

This function is useful when you need to generate a particular response to an exception at runtime.

error_type: The designated error type for this error. It only works with the E_USER family of constants, and will default to E_USER_NOTICE.

Возвращаемые значения
