我目前正在完成Zend 3教程。唯一的区别是我使用的是一个Examples表/类而不是Albums。除了每次尝试访问开发服务器时出现以下错误，所有内容似乎都符合规范：

                },

                },
            ],
        ];

使用example.php

namespace Example\Model;

class Example

    public $id;
    public $name;
    public $description;
    public $web_url

    public function exchangeArray(array $data)
    {
        $this->id     = !empty($data['id']) ? $data['id'] : null;
        $this->name = !empty($data['name']) ? $data['name'] : null;
        $this->description  = !empty($data['description']) ? $data['description'] : null;
        $this->web_url  = !empty($data['web_url']) ? $data['web_url'] : null;
    }
}

我已经包含了一切，因为我真的不确定问题出在哪里。任何帮助将不胜感激。

您的module.config.php文件需要：

use Zend\Router\Http\Segment;

靠近顶部的

声明，用于创建稍后在文件中使用的Segment别名。目前，因为这不存在，PHP正在您声明的命名空间中寻找该类（所以Example\Segment），这是不存在的。
