基于psr的规范,使用命名空间和spl_autoload_register()来实现自动加载
文件结构:
|–Api
|–Account.php
|–User.php
|–Service
|–Login.php
|–User.php
|–Application.php
Application.php
<?php use Api/User; use Service/User as User2; class Application{ public static function main(){ self::registe(); new User(); new User2(); } public static function registe(){ spl_autoload_register("Application::loadClass"); } public static function loadClass($class){ $class=str_replace('//', '/', $class); $class="./".$class.".php"; require_once $class; } } Application::main();
Api/User.php
<?php namespace Api; use Service/Login; class User{ public function __construct(){ echo "User类<br/>"; new Login(); new Account(); } }
Api/Account.php
<?php namespace Api; class Account{ public function __construct(){ echo "Account类<br/>"; } }
Service/Login.php
<?php namespace Service; class Login{ public function __construct(){ echo "Login类<br/>"; } }
Service/User.php
<?php namespace Service; class User{ public function __construct(){ echo "Service下的User类<br/>"; } }
结果:
