IIS环境
我们以php安装目录c:\php为例,首先找到c:\php\sapi\php4ts.dll文件,拷贝到windows系统目录(WindowsXP中为%windows%/system32目录)。 在IIS中添加文件关联,将.php文件映射到c:\php\sapi\php4isapi.dll。 然后编辑c:\php\php.ini文件,通过查找功能找到register_globals字符串,修改等于号后面的Off为On,该设置将打开session功能。同理找到extension_dir选项,设置为c:\php\extensions,再找到session.save_path选项,设置为c:\tmp,你要保证该文件夹存在,如果不存在,就新建一个。并将php.ini文件拷贝到windows安装目录(%windows%)下, 重新启动系统,php网站就可以工作了
apache环境
打开httpd.conf
添加php类型:AddType application/x-httpd-php .php
设置php目录:ScriptAlias /php/ "D:/Apache Group/php-4.4.0-Win32/"
设置默认文档:DirectoryIndex index.html index.html.var index.php default.php 安装gd图形库
将%php%/extension目录下的php_gd2.dll拷贝到%windir%/system32/ 设置php.ini中;extension=php_gd2.dll ,将之前的分号去掉,保存php.ini 重新启动web服务器 调用phpinfo()函数,如果其中出现gd段设置信息,则表示安装成功

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
