在php7中，有許許多多的擴充類，今天我們就以person類為例實作doing方法和saying方法，有需要的小夥伴可以參考一下。
1.需要實作的細節
實作一個person類別
實作一個doing方法和saying方法
2.第一個擴充
2.1建立類別的擴充：
[root@bogon ext]# cd /usr/local/src/php-7.0.3/ext [root@bogon ext]# ./ext_skel --extname=person
2.2 修改設定
[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])
變更為：
PHPARGWITH(person, for person support, dnl Make sure that the comment is aligned: [ --with-person Include person support])
2.3 實作程式碼
在php_person.h頭中加上
extern zend_class_entry *person_ce; PHP_METHOD(person_ce,__construct); PHP_METHOD(person_ce,saying); PHP_METHOD(person_ce,doing);
在person.c頭中加上
/** * 声明构造函数 *
@param * @return */
ZEND_METHOD(person,__construct){
zval *pThis;
pThis = getThis();
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");
}
//这个函数需要加上声明，去掉了没用的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[] */
};
//将类和方法注册到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;
}2.4 編譯
* [root@bogon hello]# [root@localhost person]# ./configure && make && make install
2.5 擴充安裝
改更php.ini 加上
[person] extenstion=person.so
2.6 擴充使用
[root@bogon tests]# cat test.php <?php $n = new person(); echo $n->saying(); echo $n->doing(); [root@localhost tests]# php test.phpconstructsayingdoingdestruct
