spl_autoload_register的自动加载学习

要加载的类：

<?php

/** * @Author: Luhix * @Date:   2017-09-13 18:32:21 * @Last Modified by:   Luhix * @Last Modified time: 2017-09-13 18:40:45 */class Test {    public function index() {        echo "类的自动加载学习";    }}

php代码：

<?php/** * @Author: Luhix * @Date:   2017-09-13 18:32:57 * @Last Modified by:   Luhix * @Last Modified time: 2017-09-13 18:39:33 */function  loadPrint($class) {    $file = $class . '.class.php';    if(is_file($file)) {        require "$file";    }}spl_autoload_register('loadPrint');$t = new Test();$t->index();

输出结果： 类的自动加载学习
