ext_skel是php源码包里自带的一个开发生成工具
使用它可以用C++编译出可用的.so库,增加函数以扩展php的功能
首先从官方下载源码
将其用tar -zxvf解压
首先我们需要建立一个xxx.skel文件,里面是我们要定义的扩展函数的声明
比如 `string bingo(string str)
然后进入到php源码包的ext目录下
使用命令
./ext_skel --extname=bingo --proto=/home/bingo.skel
来生成一个框架包然后修改config.m4文件
注释掉PHP_ARG_WITH或PHP_ARG_ENABLE（根据实际情况二选一，第一种是指扩展需第三方库支持）所以一般我们保留第二种
修改phpext.c文件 注释掉默认的函数,并编写我们的bingo函数
用phpize创建配置，在phpext下运行:
/opt/lampp/bin/phpize./configure --with-php-config=/opt/lampp/bin/php-config
并进行安装
makemake testmake install clean
#接下来的步骤由于kali各种奇奇怪怪的原因不能进行,下次再看咯
在/xxx/php/下对应的文件夹内将多出一个叫binso.so的文件
找到php.ini或extensions.ini，在其中加入一行
extension=bingo.so

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AMIn 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.
Explain how to use sessions for user authentication.Apr 26, 2025 am 12:04 AMThe 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.

What are some common problems that can cause PHP sessions to fail?Apr 25, 2025 am 12:16 AMReasons for PHPSession failure include configuration errors, cookie issues, and session expiration. 1. Configuration error: Check and set the correct session.save_path. 2.Cookie problem: Make sure the cookie is set correctly. 3.Session expires: Adjust session.gc_maxlifetime value to extend session time.
How do you debug session-related issues in PHP?Apr 25, 2025 am 12:12 AMMethods to debug session problems in PHP include: 1. Check whether the session is started correctly; 2. Verify the delivery of the session ID; 3. Check the storage and reading of session data; 4. Check the server configuration. By outputting session ID and data, viewing session file content, etc., you can effectively diagnose and solve session-related problems.
What happens if session_start() is called multiple times?Apr 25, 2025 am 12:06 AMMultiple calls to session_start() will result in warning messages and possible data overwrites. 1) PHP will issue a warning, prompting that the session has been started. 2) It may cause unexpected overwriting of session data. 3) Use session_status() to check the session status to avoid repeated calls.
How do you configure the session lifetime in PHP?Apr 25, 2025 am 12:05 AMConfiguring the session lifecycle in PHP can be achieved by setting session.gc_maxlifetime and session.cookie_lifetime. 1) session.gc_maxlifetime controls the survival time of server-side session data, 2) session.cookie_lifetime controls the life cycle of client cookies. When set to 0, the cookie expires when the browser is closed.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
