name, which is the key to implement __autoload in a system. However, a system may be developed by different people, if there is no agreed standard before development, there may be different corresponding rules, resulting in the need to implement a variety of load rules in __autoload (), it may lead to the __autoload () function is very bloated. To solve this problem, PHP also provides an automatic loading mechanism---spl_autoload_register ().

Spl_autoload and spl_autoload in php
SPL has two different functions: spl_autoload and spl_autoload_call. Different automatic loading mechanisms are implemented by pointing autoload_func to these two function addresses.
Spl_autoload is the default automatic loading function implemented by SPL, and its functions are relatively simple. It can receive two parameters. The first parameter is $ class_name, indica
