restore_exception_handler — Restores the previously defined exception handler function

### Description

bool restore_exception_handler ( void )

### Return Values

This function always returns `TRUE`.

### Examples

Example #1 restore_exception_handler() example

`<?php
function exception_handler_1(Exception $e)
{
echo '[' . __FUNCTION__ . '] ' . $e->getMessage();
}
function exception_handler_2(Exception $e)
{
echo '[' . __FUNCTION__ . '] ' . $e->getMessage();
}
set_exception_handler('exception_handler_1');
set_exception_handler('exception_handler_2');
restore_exception_handler();
throw new Exception('This triggers the first exception handler...');
