Web Application Development with PHP 4.0

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 9.11 to add members to your object.

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.
