HomeBackend DevelopmentPHP Tutorialwindows下开发并编译PHP扩展的方法_php技巧

现在就简单说一在WINDOWS下开发PHP扩展的步骤:
首先需要准备的软件有:
cygwin 安装路径e:\app\cygwin
visual studio C++ 6.0,
修改环境变量,把已经安装好的PHP路径设置为环境变量。在这里,假设我的PHP安装目录是:e:\app\php5.2.5,那么我把WINDOWS环境变量后面加上这个安装目录。方便一会儿使用php.exe。
PHP源代码,这里假设为e:\c_source_code\php-5.2.5

1、修改文件 “PHP源文件目录/ext/ext_skel_win32.php”,在这里就是:E:\c_source_code\php-5.2.5\ext,其中主要是修改其中的cygwin路径。$cygwin_path = 'e:\app\cygwin\bin';
把$cygwin_path修改为你实际安装cygwin的路径。
2、在源代码ext目录也就是e:\c_source_code\php-5.2.5\ext下,执行 php ext_skel_win32.php --extname=,此时会在ext目录下生成目录,这个目录就是我们将要进行PHP扩展开发的框架。比如你运行php.exe ext_skel_win32.php --extname=foo,会在ext目录下生成foo目录。
3、将php-root\dev\php5ts.lib拷贝至 “ext/”中。比如你要开发的PHP扩展名为foo,那么就需要把php-root\dev\php5ts.lib拷贝到PHP源文件目录ext\foo中。
4、修改foo.c内容,编写我们需要的C代码。
5、进入目录,打开.dsp。
设置VC6工程,
设置菜单“组建”->“移除工程配置”,选中“Win 32 Release_TS”,
设置菜单“工程”,选中“Win 32 Release_TS”
打开Tab“连接”,设置“输出文件名”中的目录,
[可选]打开Tab“C/C++”,增加“预处理器定义”“,COMPILE_DL_”(注意全大写,默认加入的),取消预定义“LIBZEND_EXPORTS”(否则不可引入zend函数)。
6、设置好以后,进行编译,会生成一个dll文件,文件名是.dll,比如在我们的例子中就为foo.dll
把foo.dll拷到e:\app\ext目录下,并在php.ini里加上一行extension=foo.dll,重启一下apache,查看phpinfo();,会发现我们的PHP扩展foo()已经加载进来,已经可以使用这个foo扩展了。

Beyond the Hype: Assessing PHP's Role TodayBeyond the Hype: Assessing PHP's Role TodayApr 12, 2025 am 12:17 AM

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

What are Weak References in PHP and when are they useful?What are Weak References in PHP and when are they useful?Apr 12, 2025 am 12:13 AM

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

Explain the __invoke magic method in PHP.Explain the __invoke magic method in PHP.Apr 12, 2025 am 12:07 AM

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP Community: Resources, Support, and DevelopmentThe PHP Community: Resources, Support, and DevelopmentApr 12, 2025 am 12:04 AM

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP vs. Python: Understanding the DifferencesPHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP: Is It Dying or Simply Adapting?PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The Future of PHP: Adaptations and InnovationsThe Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
