Automatic loading implementation method of PHP class

This article mainly shares with you a little knowledge about automatic loading of PHP classes. There is no need to manually add the require_once file, and the __autoload($class) function is used. I hope it can help everyone.

<?php 
spl_autoload_register(&#39;autoload1&#39;);   //&#39;autoload&#39;为定义的自动载入函数名
function __autoload1($class) {
require_once __DIR__.&#39;/&#39;.$class.&#39;.php&#39;;
}
?>
