新建一个test.php

<code><?php echo file_get_contents("http://test1.xiaoci.com/create.php");
?>
</code>

然后访问test.php,结果报错如下：

Warning: file_get_contents(http://test1.xiaoci.com/create.php) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in J:\wamp\www\long\wwwroot\mytools\test\test1.php on line 3

PHP:file_get_contents failed to open stream: HTTP request failed

注意：http://test1.xiaoci.com是我在本地搭建的一个虚拟主机
在本地搭建的一个虚拟主机，配置信息如下：
http-vhost.conf

<code><virtualhost>
    DocumentRoot "d:/wamp/www/"
    ServerName test1.xiaoci.com 
</virtualhost>
</code>

hosts

<code>127.0.0.1       test1.com
127.0.0.1               test1.xiaoci.com
</code>

并且设置了404返回到index.php,所以当手动从浏览器中打开http://test1.xiaoci.com/create.php网址的时候，由于create.php是不存在的页面，所以会转到index.php，然后在index.php中进行处理。
手动打开("http://test1.xiaoci.com/create.php")情况：可以正常访问
使用file_get_contents("http://test1.xiaoci.com/create.php")：报404错误

回复内容：

新建一个test.php

<code><?php echo file_get_contents("http://test1.xiaoci.com/create.php");

</code>

然后访问test.php,结果报错如下：

<code>127.0.0.1       test1.com
127.0.0.1               test1.xiaoci.com
</code>

host难道不应该是

127.0.0.1 test1.xiaoci.com

么，我看了下外网的那个网址确实是404，目测是你戳到外网去了，host没兜住

What is a session in PHP, and why are they used?May 04, 2025 am 12:12 AM

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.

What is the difference between absolute and idle session timeouts?May 03, 2025 am 12:21 AM

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.

What steps would you take if sessions aren't working on your server?May 03, 2025 am 12:19 AM

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.
