php7 类的方法传参

• 实现一个person类 ，实现一个doing方法和saying方法

• 在构造方法中传递一个数组，在doing中打印此数组

• saying方法中，构建一个空数组，返回，不需要传参。

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

[root@bogon ext]# ./ext_skel --extname=person

[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])

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

ZEND_BEGIN_ARG_INFO_EX(global_config_arg, 0, 0, 1)    ZEND_ARG_INFO(0, global_config)ZEND_END_ARG_INFO()ZEND_METHOD(person,__construct){    zval *array_config;    if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "a", &array_config) == FAILURE) {        RETURN_NULL();        }    //php_var_dump( &array_config,1 TSRMLS_CC);    zend_update_property(person_ce, getThis(), "config", sizeof("config")-1, array_config TSRMLS_CC);}ZEND_METHOD(person,__destruct){    zend_printf("destructn");}ZEND_METHOD(person,doing){    //array_init(return_value);    zval  *array_config;    zval  rv; //php >=7.0    array_config = zend_read_property(person_ce, getThis(), "config", sizeof("config")-1, 0, &rv TSRMLS_DC);    if( Z_TYPE_P(array_config) == IS_NULL || Z_TYPE_P(array_config) != IS_ARRAY ){        //zend_error(E_ERROR, "framework config error!");        RETURN_FALSE;    }   //php_var_dump(&array_config, 1 TSRMLS_CC);    RETURN_ZVAL(array_config, 1, 0);   //zend_printf("doingn");}ZEND_METHOD(person,saying){    if (zend_parse_parameters_none() == FAILURE) {        RETURN_FALSE;    }    array_init(return_value);    //zend_printf("sayingn");}//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  };//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;}

* [root@bogon hello]# [root@localhost person]# ./configure && make && make install

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