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

Figure 33-8. Table 9.11. Zend's API for Object Creation
Note: All functions in Table 9.11 work on the object "object" with the key "key". The key forms the member name, so the resulting member can be accessed via $object->key. |
| 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. |
