// Merge both decks print_r ( $deck -> merge ( $deck2 ));  
?>
Exit:
Elements of first deque DsDeque Object ([0] = > engineer [1] = > for [2] = > engineer) Elements of second deque DsDeque Object ([0] = > practicing [1] = > data [2] = > structures) Merged deque elements DsDeque Object ([0] = > engineer [1] = > for [2] = > engineer [3] = > practicing [4] = > data [5] = > structures)
