I don-t see all this need to study the case, it's pretty simple, as is that operation, in PHP. In other languages, could have been the same, rarely in scripting languages though, at least those with still primitive scalar values (int, float, string, bool) Regards _________________________________________________________________ Windows Live Hotmail: Your friends can get your Facebook updates, right from Hotmail®. http://www.microsoft.com/middleeast/windows/windowslive/see-it-in-action/social-network-basics.aspx?ocid=PID23461::T:WLMTAGL:ON:WL:en-xm:SI_SB_4:092009
