如何在php-extension中将php对象保存到哈希表？

Question

如何将php对象保存到hashtable中，以及如何在php-extension中从hashtable中获取保存的php obejct？

下面是我的代码：

//object_map has been init and alloc memory
//return_value is the return var of PHP_FUNCTION

zend_class_entry **class_ce,
object_init_ex(return_value, *class_ce); //create object
ioc_add_object_to_hash(name, return_value ); //save object

//find in the hashtable
if( zend_hash_find( object_map, name, sizeof(name), (void*)&return_value ) == SUCCESS ){

    php_printf("return_value:%p, %p,type:%d\n", return_value,&return_value, Z_TYPE_P(return_value));
    return 0;
}

//definition of ioc_add_object_to_hash
int ioc_add_object_to_hash( const char *name, zval *obj )
{
    if( !obj ){
        return -1;
    }
    if( !object_map ){
        return -1;
    }
    if( zend_hash_update( object_map, name, sizeof(name), obj, sizeof(*obj), NULL) == SUCCESS ){
        return 0;
    }
    return -1;
}

PHP代码：

   $filelist = array(
       "Foo" => realpath(__DIR__)."/Foo.php",
       "Bar" => realpath(__DIR__)."/Bar.php",
   );

   ioc::init( $filelist );


  var_dump(get_included_files());

  Bar::halo();

  $foo = ioc::make("Foo");

  echo $foo->get();

  $foo2 = ioc::make("Foo"); var_dump($foo2);

第二次调用ioc：：make(“Foo”)后$foo2为空；

我所有的代码都是推送到https://github.com/longmon/php-ioc.git的。

谢谢!

嘿，我自己解决了！我的目的是从哈希表中获取对象，问题是我错误地初始化了return_value，所以我正确地获取了NULL.The，如下所示：

if( !object_map ){
    php_error_docref(NULL TSRMLS_CC, E_NOTICE, "object_map had not been alloced");
    return -1;
}
zval **obj;
if( zend_hash_find( object_map, name, sizeof(name), (void **)&obj ) == SUCCESS ){
    Z_TYPE_P(return_value)   = IS_OBJECT;
    Z_OBJVAL_P(return_value) = Z_OBJVAL_PP(obj);
    //zval_ptr_dtor(obj);
    return 0;
}
return -1;

关键的一行是：

Z_TYPE_P(return_value)   = IS_OBJECT;
Z_OBJVAL_P(return_value) = Z_OBJVAL_PP(obj);
