如何使用ZipArchive new时候 thinkphp 3.2.3提示找不到类 php5.5.12 默认是开启了zip的啊?
怕说的不清楚 phpinfo 查看的是打开了zip啊 



查看php官方文档 看别人 都是直接new的

  $zip = new ZipArchive;

这个类不是扩展安装了直接可以用的么
thinkphp3.2.3

<br />public  function  tozip(){<br />        $zip =new ZipArchive;<br />        dump($zip);<br />    }<br />

我这提示找不到类额

:(
Class 'Home\Controller\ZipArchive' not found
错误位置
FILE: D:\wamp\www\apps\Home\Controller\PictureController.class.php  LINE: 244

我看php文档里 要求就是
(PHP 5 >= 5.2.0, PECL zip >= 1.1.0)
应该是可以使用的啊  5.5.12 也集成的 给的例子 也是直接new的 请问 我这是哪里的问题呢

------解决思路----------------------
这是因为你使用了命名空间的原因
ZipArchive 类是php内置类并不在 Home\Controller 中
你使用时要加上 \
$zip =new \ZipArchive;
就可以了

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.
