Newbie Question - Updating Object Properties in the Hash

I am new to php development and am having the following problem - I have a function which is registered as a method for an object. In this method I am attempting to update a property of the object but can't seem to get it working right. Here is what I am doing: I add the string property and the method to the object in the function that serves as a constructor like this: object_init(return_value); add_property_string(return_value, "m_cPrefValue", value->value.str.val,1); add_method(return_value, "getuserpreference", PHP3_GetUserPreference); return; In the getuserpreference method I then need to store a new value for the property m_cPrefValue so I try this: pval * cPrefValue; getThis(&id); _php3_hash_update(id->value.ht, "m_cPrefValue", sizeof("m_cPrefValue"), "newstring" , sizeof("newstring"), (void **)&cPrefValue); But that doesn't change the value in the hash because when I then access the property in the php script - i get the unupdated value. I am able to get the property from within the function using: _php3_hash_find(id->value.ht,"m_cPrefValue", sizeof("m_cPrefValue"),(void **)&cPrefValue); If anyone could let me know what I am doing wrong I would very much appreciate it.
