回复讨论(解决方案)
经测试,没有问题。
为啥我的不行
迅雷什么的?有可能文件下载回来不完整
那个图片打开来没问题的 ,就是用这测试的代码 下载的就不行
截个图看看。
另外,你是用什么打开的。代码运行环境是?
测试过,一切正常。
win7的图片查看器
谷歌浏览器 apache php5.3
E/Apache/htdocs 目录下存在qq.jpg文件吗?
是的 就是看不到....
用记事本打开图片文件,看看有什么。
一堆乱码
你的代码中有 $file_path=iconv("utf-8","gb2312",$file_name);
表示你的 php 工作在 window 系统中
而 window 系统是严格区分文本文件和二进制文件的
而你却用 $fp=fopen($file_path,"r"); 以文本方式打开二进制文件
于是,因为你违规了,所以得不到正确的结果
你需要用二进制方式打开二进制文件 $fp=fopen($file_path,"r b");
另外,你的 utf-8 编码的程序文件,需要以无 BOM 头的格式进行保存
谢谢了, 换成无BOM头的格式保存就可以了

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
