// Show Deque elements print_r ( $deck_new );  
?>
Exit:
Elements of Deque DsDeque Object ([0] = > 1 [1] = > 2 [2] = > 3 [3] = > 4 [4] = > 5 [5] = > 6) Deque after slicing: DsDeque Object ([0] = > 3 [1] = > 4 [2] = > 5 [3] = > 6)
Program 2:  
// Declare deque $deck = new DsDeque ([1, 2, 3, 4, 5, 6]); echo ( " Elements of Deque " );  
// Show Deque elements print_r ( $deck );  
// slicing decks from 3 to -2 $deck_new = $deck -> slice (3, -2); echo ( " Deque after slicing: " );  
// Show Deque elements print_r ( $deck_new );  
?>
Exit:
Elements of Deque DsDeque Object ([0] = > 1 [1] = > 2 [2] = > 3 [3] = > 4 [4] = > 5 [5] = > 6) Deque after slicing: DsDeque Object ([0] = > 4)
