用c扩展你的php

看看现在多少网站用的是php,可以去搜索看看,看后你就吓到了,希望大家一起热爱php。

小弟刚学扩展,小牛试刀一下

1。下载好php,解压,cd ext

ls

发现有个蓝色的文件,说明是可执行的

./ext_skel --extname=robert(此处可随便命名,本人英文名robert)

运行后会新生成一个文件夹

2。打开新生成的文件夹

打开config.m4 文件后,找到 PHP_ARG_WITH行,并去掉那三行前得 dnl,dnl 是注释符。

:wq

3. 打开php_luoxin.h 文件,找到PHP_FUNCTION位置,添加我们自己的定义函数,我们新加了两个函数, luoxin,robert,,添加的代码是:

PHP_FUNCTION( luoxin )

PHP_FUNCTION( robert )

:wq

3. jerry.c文件时核心文件,是实现函数逻辑的定义文件。在 156 行左右,参照 confirm_jerry_compiled 函数,来写我们新加函数的逻辑代码,这儿只是简单的输出字符, c 高手可以写更强大的逻辑函数,以满足自己的需要。

PHP_FUNCTION(luoxin){zend_printf("This is luoxin function");}

PHP_FUNCTION(robert){zend_printf("This is robert function");}

在文件中找到luoxin_functions 函数,在其内 添加我们先前设置的两个函数, luoxin,robert,添加的代码是:

PHP_FE(luoxin,NULL)

PHP_FE(robert,NULL)

注意要填在{NULL,NULL,NULL} 之前。

:wq

4.用phpize编译,后面跟安装memcache一样

很简单,可以用上自己写的模块了,呵呵

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
