How to write php7 extension class

In php7, there are many extension classes. Today we will take the person class as an example to implement the doing method and saying method. Friends in need can refer to it.

1. Details that need to be implemented

Implement a person class

Implement a doing method and a saying method

2. The first extension

2.1 Create an extension of the class:

[root@bogon ext]# cd /usr/local/src/php-7.0.3/ext
[root@bogon ext]# ./ext_skel --extname=person

2.2 Modify the configuration

[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])

to:

PHPARGWITH(person, for person support,
dnl Make sure that the comment is aligned:
[ --with-person Include person support])

2.3 Implementation code

Add

extern zend_class_entry *person_ce;
PHP_METHOD(person_ce,__construct);
PHP_METHOD(person_ce,saying);
PHP_METHOD(person_ce,doing);

to the php_person.h header. Add

/** * 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;
}

to the person.c header. 2.4 Compile

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

2.5 Extension installation

Change php.ini and add

[person] extenstion=person.so

2.6 Extended use

[root@bogon tests]# cat test.php
<?php
$n = new person();
echo $n->saying();
echo $n->doing();
[root@localhost tests]# php test.phpconstructsayingdoingdestruct
