Restores the previous error handler function
Description
restore_error_handler(): true
Pops the error handler that was active before the most recent call to set_error_handler() off the internal stack of error handlers and makes it active again, together with the error_levels mask it was registered with. The restored handler could be the built-in or a user defined function.
Calling this function more often than set_error_handler() leaves the built-in error handler active; no error is raised.

Return Values
Always
