如何制作一个php扩展

一、安装php

假如把php安装/usr/local/php下

二、php扩展框架工具

进入 /php源码/ext 目录

执行

./ext_skel --extname=my_module

显示结果

Creating basic files: config.m4 config.w32 .svnignore my_module.c php_my_module.h CREDITS EXPERIMENTAL tests/001.phpt my_module.php [done].

To use your new extension, you will have to execute the following steps:

1.  $ cd ..

2.  $ vi ext/my_module/config.m4

3.  $ ./buildconf

4.  $ ./configure --[with|enable]-my_module

5.  $ make

6.  $ ./sapi/cli/php -f ext/my_module/my_module.php

7.  $ vi ext/my_module/my_module.c

8.  $ make

Repeat steps 3-6 until you are satisfied with ext/my_module/config.m4 and

step 6 confirms that your module is compiled into PHP. Then, start writing

code and repeat the last two steps as often as necessary.

其实这里就教了你怎么操作了

在当前目录再执行 cd my_module/ 进入我们的模块目录

然后我们要修改文件顺序是

configue.m4

my_module.c

php_my_module.h

修改configue.m4

根据你自己的选择将

dnl PHP_ARG_WITH(my_module, for my_module support,

dnl Make sure that the comment is aligned:

dnl [  --with-my_module             Include my_module support])

修改成

PHP_ARG_WITH(my_module, for my_module support,

Make sure that the comment is aligned:

[  --with-my_module             Include my_module support])

或者将

dnl PHP_ARG_ENABLE(my_module, whether to enable my_module support,

dnl Make sure that the comment is aligned:

dnl [  --enable-my_module           Enable my_module support])

修改成

PHP_ARG_ENABLE(my_module, whether to enable my_module support,

Make sure that the comment is aligned:

[  --enable-my_module           Enable my_module support])

其实就是去掉前面的dnl

修改my_module.c

将文件其中的下列代码进行修改

/* Every user visible function must have an entry in my_module_functions[].

*/

function_entry my_module_functions[] = {

PHP_FE(say_hello,       NULL)  /* ?添加着一行代码 */

PHP_FE(confirm_my_module_compiled,      NULL) /* For testing, remove later. */

{NULL, NULL, NULL}      /* Must be the last line in my_module_functions[] */

};

在文件的最后添加下列代码

PHP_FUNCTION(say_hello)

{

zend_printf("hello world/n");

}

修改php_my_module.h

在PHP_FUNCTION(confirm_my_module_compiled ); /* For testing, remove later. */

添加一行：

PHP_FUNCTION(say_hello); /* For testing, remove later. */

三、执行

/usr/local/php/bin/phpize

四、编译安装扩展

然后执行./configure --enable-my_module --with-php-config=/usr/local/php/bin/php-config
