php扩展开发2--添加类

1.需要实现的细节

实现一个person类
实现一个doing方法和saying方法

2.第一个扩展

2.1创建类的扩展：

[root@bogon ext]# cd /usr/local/src/php-7.0.3/ext

[root@bogon ext]# ./ext_skel --extname=person //运行ext_skel创建扩展的开发包

2.2 修改配置

[root@bogon ext]# vim person/config.m4

dnl PHPARGWITH(person, for person support,
dnl Make sure that the comment is aligned:
dnl [ --with-person Include person support])
更改为：
PHPARGWITH(person, for person support,
dnl Make sure that the comment is aligned:
[ --with-person Include person support])
****dnl 在这是注释的意思。去掉dnl 就是打开这一行的意思

2.3 实现代码

在php_person.h头中加上

extern zend_class_entry *person_ce;

PHP_METHOD(person_ce,__construct);

PHP_METHOD(person_ce,saying);

PHP_METHOD(person_ce,doing);

在person.c头中加上

/*定义类*/

zend_class_entry *person_ce;

/**

 * 声明构造函数

 * @param

 * @return

 */

ZEND_METHOD(person,__construct){

    zend_printf("construct\n");

}

/**

 * 声明析造函数

 * @param

 * @return

 */

ZEND_METHOD(person,__destruct){

    zend_printf("destruct\n");

}

ZEND_METHOD(person,doing){

    zend_printf("doing\n");

}

ZEND_METHOD(person,saying){

    zend_printf("saying\n");

}

/*NULL  表示不传参数
*

*　　ZEND_ACC_PUBLIC  说明是public  方法

* ZEND_ACC_CTOR  说明是构造函数
* ZEND_ACC_DTOR  说明是析构函数
*/

const zend_function_entry person_functions[] = {

    ZEND_ME(person, __construct,NULL, ZEND_ACC_PUBLIC|ZEND_ACC_CTOR)

    ZEND_ME(person,doing,NULL,ZEND_ACC_PUBLIC) ZEND_ME(person,saying,NULL,ZEND_ACC_PUBLIC)

    ZEND_ME(person,__destruct,NULL,ZEND_ACC_PUBLIC|ZEND_ACC_DTOR)

    PHP_FE_END  /* Must be the last line in person_functions[] */

};

//将类和方法注册到zend

PHP_MINIT_FUNCTION(person)

{

       zend_class_entry ce;

       INIT_CLASS_ENTRY(ce, "person", person_functions);

       person_ce = zend_register_internal_class(&ce TSRMLS_CC);

       zend_declare_property_null(person_ce,"saying",strlen("saying"),ZEND_ACC_PUBLIC);

       zend_declare_property_null(person_ce,"doing",strlen("doing"),ZEND_ACC_PUBLIC);

    return SUCCESS;

}

执行命令 phpize

./configure

make

make install 或者手动cp

改更php.ini 加上[person] extenstion=person.so

使用扩展：

[root@bogon tests]# cat test.php

<?php

$n = new person();

echo $n->saying();

echo $n->doing();

[root@localhost tests]# php test.php

construct

saying

doing

destruct
