  2. btw there is circular queuing beside normal queuing how about that ? how do they work ? is there any different ways to queuing?

  3. im useing php, is there a simple ( very simple or easy to read ) sample code that i can learn on ( links are okay too. )?

  4. there is pop, push and etc ( stacking and queuing ), is there anything like that in php ?

    1: While with stacks the insert/removal operations both work on the same end of the data structure (top)

    with queues the insertion takes place at one end (rear) and the removal at the other end (front).

    (Both images are from the respective wikipedia entries)

    2: see http://en.wikipedia.org/wiki/Circular_buffer

    3: and 4: see SplStack and SplQueue
