set_error_handler() doesn’t work for FATAL error

Nope, that’s just a limitation of set_error_handler(); it doesn’t handle all errors.

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.

The register_shutdown_function() and error_get_last() is a decent workaround.
