Windows中搭建PHP扩展开发环境
一、提前准备
二、编译PHP
首先下载php-sdk,先下载较新的php-sdk-binary-tools-20110915.zip,解压到
f:\php_stdio\php-sdk
目录下。注意,解压后,这个目录下应该有bin和script子目录。
开一个cmd窗口,切换到f:\php_stdio\php-sdk目录下,运行vcvarsall.bat来设置好编译环境变量。
VS2008安装路径\VC\vcvarsall.bat
这里vcvarsall.bat的具体目录要根据你自己的安装位置而定。
接着,进入在cmd窗口里继续运行以下命令:
bin\phpsdk_setvars.bat
bin\phpsdk_buildtree.bat php54dev
这样,在f:\php_stdio\php-sdk目录下又多了一个php54dev目录。
接着继续将deps解压到
f:\php_stdio\php-sdk\php54dev\vc9\x86\
目录下。原来这个目录下的deps目录下的所有子目录均是空目录,解压后,应该复制进很多必要的模块/扩展所需的库文件。
接下来,将PHP-5.4.5源码目录复制一份到
f:\php_stdio\php-sdk\php54dev\vc9\x86\
目录下。进入php源码目录
cd f:\php_stdio\php-sdk\php54dev\vc9\x86\php-5.4.5
运行
buildconf
然后就可以先试着编译php了。最开始,一般编译尽可能少的模块,先让核心能正常编译出来:
configure --disable-all --enable-cli
这一步的主要目的是生成config.w32.h,如果需要生成PHP,可以继续执行
三、创建新扩展my_fopen


cd f:\php_stdio\php-sdk\php54dev\vc9\x86\php-5.4.5\extphp ext_skel_win32.php --extname=my_fopen




四、编译、使用扩展


五、编译新扩展遇到的问题
mspdbsrv.exe 或 mspdbcore.dll 丢失或者其版本和 mspdb80.dll 的版本不同,确定这三个文件的相同版本安装在系统里。
在VC安装目录下的\Common7\IDE 目录下拷贝这三个文件到 安装目录下的VC\bin下即可
2. ../main/config.w32.h打开失败
PHP源码进行configure后才会产生config.w32.h
3.无法打开输入文件“php5ts.lib”
设置工程属性页中的C++->高级->编译为改为编译为C代码(/TC),链接器->附加库目录加一项PHP二进制包的dev目录。

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.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
