__autoload(PHP 5, PHP 7)
__autoload — Attempt to load undefined class
Warning
This feature has been DEPRECATED as of PHP 7.2.0. Relying on this feature is highly discouraged.
__autoload函数在php7.2废弃，所以要用 spl_autoload_register 函数替代
https://www.php.net/manual/en/function.spl-autoload-register.php
spl_autoload_register(PHP 5 >= 5.1.0, PHP 7)
spl_autoload_register — Register given function as __autoload() implementation

autoload.php 只需要改一行
$baseDir = dirname(__FILE__).'/vendor/'.str_replace('\\', '/', $prefix);
