Objects

Since objects can be converted to arrays (and vice versa), you might have already guessed that they have a lot of similarities to arrays in PHP. Objects are maintained with the same hash functions, but there's a different API for creating them.

To initialize an object, you use the function object_init():
zval *new_object; MAKE_STD_ZVAL(new_object); if(object_init(new_object) != SUCCESS) { // do error handling here }
You can use the functions described in Table 34-4 to add members to your object.

Function	Description
*add_property_long(zval object, char key, long l);()*	Adds a long to the object.
*add_property_unset(zval object, char key);()*	Adds an unset property to the object.
*add_property_bool(zval object, char key, int b);()*	Adds a Boolean to the object.
*add_property_resource(zval object, char key, long r);()*	Adds a resource to the object.
*add_property_double(zval object, char key, double d);()*	Adds a double to the object.
*add_property_string(zval object, char key, char str, int duplicate);()**	Adds a string to the object.
*add_property_stringl(zval object, char key, char str, uint length, int duplicate);()**	Adds a string of the specified length to the object. This function is faster than add_property_string() and also binary-safe.
*add_property_zval(zval obect, char key, zval container):()**	Adds a `zval` container to the object. This is useful if you have to add properties which aren't simple types like integers or strings but arrays or other objects.
