Extracting values from an array?

Hi, I have an array as follows, I need only array[2] and array[3], how can I extract only these two array? Some time there will be more than two hosts, in essence I need all the array values between array[1] and the array that that has the string "registrations.". How can I do this?

Array
(
    [0] => Privilege: Command
    [1] => Host          username       password                          
    [2] => host01       user1             pw01            
    [3] => host02       user2             pw02        
    [4] => 2  registrations.
    [5] =>
    [6] => Follows
)

Thanks of the help.
