PHP5手动最简安装方法_PHP
系统要求
win2000 advanced server
iis5.0
php5rc2
第一步
当然是先要从 上下个php-5.0.3-Win32.zip回来。偶下的是php-5.0.3RC2-Win32.zip其实和php-5.0.3-Win32.zip差不多就少了两注册表文件,不过根本用不上,那是为iis4以下版本准备的 。
第二步
解压到任意目录,比如n:\imp\php\php5.0.3 不过不要在目录名里面有空格,以免出一些小麻烦。像e:\program files\php这样设置目录就不大妥当。
第三步
把你刚解压的目录名加到系统环境变量path里面。系统环境变量的不知道?晕倒!桌面-〉我的电脑-〉鼠标右键-〉属性-〉高级-〉系统变量-〉path->编辑-〉在最后面加分号;目录名(例如:n:\imp\php\php5.0.3)-〉确定。
第四步
在刚添加到path中的那个目录里面找到php.ini-dist或php.ini-recommended重命名为php.ini 剪切到系统目录下 c:\winnt 。用后面那个省得还要自己设置。
第五步
连接php为isapi方式
确认iis5.0 工作正常。打开internet服务管理器(运行-〉inetmgr-〉在你要连接php的网站或默认网站站点-〉单击鼠标右键 -〉属性-〉主目录--〉配置--〉应用程序映射-〉添加--〉可执行文件-〉你的php目录中的php5isapi.dll-〉扩展名-〉php(php3 phtml)-〉全部动作或限于(option,get ,post ,head。。。自己加)-〉钩选 脚本引擎--〉钩选 检查文件是否存在--〉确定--〉isapi筛选器--〉添加--〉筛选器名称—〉php--〉可执行文件--〉你的php目录中的php5isapi.dll--〉确定--〉主目录--〉钩选 脚本资源访问--〉执行许可--〉脚本和可执行程序。 属性-〉文档--〉启用默认文档--〉添加 --〉index.php 。
连接php为cgi方式
在主目录添加应用程序映射为php.exe 文件后缀为php就Ok 啦 如果要支持多个后缀,重复添加。
在此种安装的时候要注意在应用程序映射的时候的路径的写法,否则会出现下面的错误信息。
CGI Timeout
The specified CGI application exceeded the allowed time for processing. The server has deleted the process.
应该在路径后面加上"%s" %s 比如你的php.exe的路径是 n:\imp\php\php5.0.3\php.exe 那么在写到应用程序映射->可执行文件时就应该这样写 n:\imp\php\php5.0.3\php.exe "%s" %s
cgi的界面就是白底黑字。安全方面也不容乐观。所以用什么方式还是你自己定吧。
重启iis,运行--〉net stop iisadmin net start w3svc
顺便介绍下运行的几个程序
cmd
inetmgr
compmgmt
第六步
编写一个测试页,也就是包含php脚本的页面
echo 'Current PHP version: ' . phpversion();
phpinfo();
phpinfo(INFO_MODULES);
?>
保存为index.php,放到刚才你连接过php的网站的主目录中。在浏览器中查看此页。比如
第七步
安装其他插件 (扩展)

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.

PHP is not dead. 1) The PHP community actively solves performance and security issues, and PHP7.x improves performance. 2) PHP is suitable for modern web development and is widely used in large websites. 3) PHP is easy to learn and the server performs well, but the type system is not as strict as static languages. 4) PHP is still important in the fields of content management and e-commerce, and the ecosystem continues to evolve. 5) Optimize performance through OPcache and APC, and use OOP and design patterns to improve code quality.

PHP and Python have their own advantages and disadvantages, and the choice depends on the project requirements. 1) PHP is suitable for web development, easy to learn, rich community resources, but the syntax is not modern enough, and performance and security need to be paid attention to. 2) Python is suitable for data science and machine learning, with concise syntax and easy to learn, but there are bottlenecks in execution speed and memory management.

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.
