下面就为大家带来一篇PHP 自动加载的简单实现(推荐)。觉得挺不错的,现在就分享给大家,也给大家做个参考。一起过来看看吧 基于psr的规范,使用和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 ApiUser;
use ServiceUser 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();ApiUser.php <?php
namespace Api;
use ServiceLogin;
class User{
public function construct(){
echo "User类<br/>";
new Login();
new Account();
}
}ApiAccount.php <?php
namespace Api;
class Account{
public function construct(){
echo "Account类<br/>";
}
}ServiceLogin.php <?php
namespace Service;
class Login{
public function construct(){
echo "Login类<br/>";
}
}ServiceUser.php <?php
namespace Service;
class User{
public function construct(){
echo "Service下的User类<br/>";
}
}结果: |
