如何在php扩展中实例化php类

#include "php.h"
#include "zend.h"

// 定义一个PHP类
zend_class_entry *my_class_entry;

// 定义一个PHP对象
typedef struct {
    zend_object std;
    // 添加其他属性
} my_object;

// 初始化函数
PHP_MINIT_FUNCTION(my_extension) {
    // 注册PHP类
    zend_class_entry ce;
    INIT_CLASS_ENTRY(ce, "MyClass", NULL);
    my_class_entry = zend_register_internal_class(&ce);

    // 设置类的属性和方法

    return SUCCESS;
}

// 创建对象函数
zend_object *my_object_create(zend_class_entry *ce) {
    my_object *obj = (my_object *)ecalloc(1, sizeof(my_object) + zend_object_properties_size(ce));
    zend_object_std_init(&obj->std, ce);
    object_properties_init(&obj->std, ce);
    obj->std.handlers = zend_get_std_object_handlers();
    return &obj->std;
}

// 销毁对象函数
void my_object_destroy(zend_object *object) {
    my_object *obj = (my_object *)((char *)object - XtOffsetOf(my_object, std));
    zend_object_std_dtor(&obj->std);
    efree(obj);
}

// 扩展的全局变量
ZEND_BEGIN_MODULE_GLOBALS(my_extension)
    // 添加其他全局变量
ZEND_END_MODULE_GLOBALS(my_extension)

// 定义扩展的全局变量
ZEND_DECLARE_MODULE_GLOBALS(my_extension)

// 扩展的初始化函数
PHP_MINIT_FUNCTION(my_extension) {
    // 注册PHP类
    zend_class_entry ce;
    INIT_CLASS_ENTRY(ce, "MyClass", NULL);
    my_class_entry = zend_register_internal_class(&ce);
    my_class_entry->create_object = my_object_create;
    memcpy(&my_object_handlers, zend_get_std_object_handlers(), sizeof(zend_object_handlers));
    my_object_handlers.offset = XtOffsetOf(my_object, std);
    my_object_handlers.free_obj = my_object_destroy;

    // 注册其他函数

    return SUCCESS;
}

// 扩展的全局变量初始化函数
static void php_my_extension_init_globals(zend_my_extension_globals *globals) {
    // 初始化全局变量
}

// 扩展的模块定义
zend_module_entry my_extension_module_entry = {
    STANDARD_MODULE_HEADER,
    "my_extension",
    NULL,
    PHP_MINIT(my_extension),
    NULL,
    NULL,
    NULL,
    NULL,
    PHP_MY_EXTENSION_VERSION,
    STANDARD_MODULE_PROPERTIES,
    PHP_GINIT(my_extension),
    php_my_extension_init_globals,
    NULL,
    NULL,
    NULL,
    STANDARD_MODULE_PROPERTIES_EX
};

// 安装扩展函数
#ifdef COMPILE_DL_MY_EXTENSION
ZEND_GET_MODULE(my_extension)
#endif
