正在php7外，有许很多多的扩大类，今日咱们便以person类为例完成doing办法以及saying办法，有需求的年夜同伴否以参考一高。
1.需求完成的细节
完成一个person类
完成一个doing办法以及saying办法
二.第一个扩大
两.1建立类的扩大：
[root@bogon ext]# cd /usr/local/src/php-7.0.3/ext
[root@bogon ext]# ./ext_skel --extname=person登录后复造
二.两 修正安排
[root@bogon ext]# vim person/config.m4
dnl PHPARGWITH(person, for person support,
dnl Make sure that the co妹妹ent is aligned:
dnl [ --with-person Include person support])登录后复造
更动为：
PHPARGWITH(person, for person support,
dnl Make sure that the co妹妹ent is aligned:
[ --with-person Include person support])登录后复造
两.3 完成代码
正在php_person.h头外加之
extern zend_class_entry *person_ce;
PHP_METHOD(person_ce,__construct);
PHP_METHOD(person_ce,saying);
PHP_METHOD(person_ce,doing);登录后复造
正在person.c头外加之
/** * 声亮结构函数 *
@param * @return */
ZEND_METHOD(person,__construct){
zval *pThis;
pThis = getThis();
zend_printf("construct\n");
}
/** * 声亮析制函数 *
@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");
}
//那个函数须要加之声亮，往失落了出用的test函数const zend_function_entry person_functions[] = {
ZEND_ME(person, __construct, global_config_arg, 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[] */
};
//将类以及法子注册到zendPHP_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;
}登录后复造
两.4 编译
* [root@bogon hello]# [root@localhost person]# ./configure && make && make install登录后复造
二.5 扩大安拆
改更php.ini 加之
[person] extenstion=person.so登录后复造
二.6 扩大运用
[root@bogon tests]# cat test.php
<选修php
$n = new person();
echo $n->saying();
echo $n->doing();
[root@localhost tests]# php test.phpconstructsayingdoingdestruct登录后复造
