PHP AutoLoad: Solve PHP in the

Recently, in the project found that the PHP __autoload method is invalid. Debugging for a long time, baffled, check the data to know that the original is Smarty reasons. The new Smarty changed the way the autoload.
The solution is to add a piece of code after the Smarty containing the class file, Spl_autoload_register ("__autoload");
As follows:
<?php
Define (' Root_path ', DirName (__file__));
Require_once Root_path. '/includes/smarty/smarty.class.php ';
Spl_autoload_register ("__autoload"); Add this piece of code
?>
