php - 使用命名空间时出错

Question

命名空间出现以下错误。我已经搜索并尝试实现我找到的所有解决方案，但我无法解决。

错误:

Fatal error: Uncaught Error: Class 'App\Models\Site\User' not found in /Applications/MAMP/htdocs/php-sem-medo/ORM/index.php on line 4

索引.php

<?php
    require_once "config.php";
    use App\Models\Site\User as User;
    $user = new User;
    dump($user -> all());
?>

模型.php

<?php
    namespace App\Models{
        class Model extends \ActiveRecord\Model { };
    }
?>

用户名.php

<?php
    namespace App\Models\Site{
        use App\Models\Model;
        class User extends Model {
            static $table_name = 'users';
        }
    }
?>

Composer .json

{
    "require": {
        "php-activerecord/php-activerecord": "^1.1"
    },
    "autoload":{
        "psr-4":{
            "App\\":"App"
        }
    }
}

配置文件

<?php
    require_once 'vendor/autoload.php'; 
    require_once 'connection.php';
?>

目录结构是

php-sem-medo -> ORM -> App -> Models-> Model.php
                 |-> APP -> Models -> Site -> User.php
                 |-> vendor -> composer
                 |-> vendor -> php-activerecord
                 |-> vendor -> autoload.php
                 |-> composer.json
                 |-> composer.lock
                 |-> config.php
                 |-> connection.php
                 |-> index.php

Answer 1

require_once()不仅需要文件名，还需要文件的完整路径。

尝试连接你的插件目录和文件名
