Data Structure Documentation

struct php_property_proxy

The internal property proxy.

Container for the object/array holding the proxied property.

Data Fields
zval *	container	The container holding the property.
size_t	member_len	The length of the name.
char *	member_str	The name of the proxied property.

struct php_property_proxy_object

The userland object.

Return an object instance of php\PropertyProxy to make your C-struct member accessible by reference from PHP userland.

Example:

static zval *my_read_prop(zval *object, zval *member, int type, zend_literal *key TSRMLS_DC)
{
    my_object_t *obj = zend_object_store_get_object(object TSRMLS_CC);
    my_prophandler_t *handler;
    zval *return_value, *copy = my_cast(IS_STRING, member);

    if (SUCCESS == my_get_prophandler(Z_STRVAL_P(copy), Z_STRLEN_P(copy), &handler)) {
        ALLOC_ZVAL(return_value);
        Z_SET_REFCOUNT_P(return_value, 0);
        Z_UNSET_ISREF_P(return_value);

        if (type == BP_VAR_R) {
            handler->read(obj, return_value TSRMLS_CC);
        } else {
            //
            // This is the interesting part
            //
            php_property_proxy_t *proxy;
            zend_object_value proxy_ov;
            zend_class_entry *proxy_ce;

            proxy = php_property_proxy_init(object, Z_STRVAL_P(copy), Z_STRLEN_P(copy) TSRMLS_CC);
            proxy_ce = php_property_proxy_get_class_entry();
            proxy_ov = php_property_proxy_object_new_ex(proxy_ce, proxy, NULL TSRMLS_CC);
            RETVAL_OBJVAL(proxy_ov, 0);
        }
    } else {
        zend_object_handlers *oh = zend_get_std_object_handlers();
        return_value = oh->read_property(object, member, type, key TSRMLS_CC);
    }

    zval_ptr_dtor(&copy);

    return return_value;
}

typedef struct php_property_proxy php_property_proxy_t

Function Documentation

void php_property_proxy_free

(

php_property_proxy_t **

proxy

)

Destroy and free a property proxy.

The destruction of the property proxy object calls this.

Parameters

proxy

a pointer to the allocated property proxy

zend_class_entry* php_property_proxy_get_class_entry

(

void

)

Get the zend_class_entry of php\PropertyProxy.

Returns

the class entry pointer

php_property_proxy_t* php_property_proxy_init	(	zval *	container,
		const char *	member_str,
		size_t	member_len
	)

Create a property proxy.

The property proxy will forward reads and writes to itself to the proxied property with name member_str of container.

Parameters

container	the container holding the property
member_str	the name of the proxied property
member_len	the length of the name

Returns

a new property proxy

zend_object_value php_property_proxy_object_new

(

zend_class_entry *

ce

)

Instantiate a new php\PropertyProxy.

Parameters

ce	the property proxy or derived class entry

Returns

the zval object value

zend_object_value php_property_proxy_object_new_ex	(	zend_class_entry *	ce,
		php_property_proxy_t *	proxy,
		php_property_proxy_object_t **	ptr
	)

Instantiate a new php\PropertyProxy with proxy.

Parameters

ce	the property proxy or derived class entry
proxy	the internal property proxy
ptr	a pointer to store the resulting property proxy object

Returns

the zval object value
