These are, in order, the error number that occurred, the string version of the error, the file the error occurred in, and the line of the error. This is where exception handling enters the picture. You can log the details of the error, including variables that were set at the time the error occurred.

Using register_shutdown_function you cannot handle an error from within the code where it was called, meaning the code would still stop working at the point where the error occurs.
