Last Updated : 14 Aug, 2019

The Ds\Deque::reversed() function is an inbuilt function in PHP which is used to return the copy of Deque which contains the elements in reversed order. Syntax:

public Ds\Deque::reversed( void ) : Ds\Deque

Parameters: This function does not accept any parameter. Return Value: This function returns a Deque which is the copy of original Deque containing the elements in reverse order. Below programs illustrate the Ds\Deque::reversed() function in PHP: Program 1:

PHP

<?php

// Declare a deque
$deck = new \Ds\Deque([10, 20, 30, 40, 50, 60]);

echo("Elements of Deque\n");

// Display the Deque elements
var_dump($deck);

// Reversing the deque
$deck_new = $deck->reversed();
 
echo("\nElements of the reversed deque\n");

// Display the Deque elements
var_dump($deck_new);

?>

Output:

Elements of Deque
object(Ds\Deque)#1 (6) {
  [0]=>
  int(10)
  [1]=>
  int(20)
  [2]=>
  int(30)
  [3]=>
  int(40)
  [4]=>
  int(50)
  [5]=>
  int(60)
}

Elements of the reversed deque
object(Ds\Deque)#2 (6) {
  [0]=>
  int(60)
  [1]=>
  int(50)
  [2]=>
  int(40)
  [3]=>
  int(30)
  [4]=>
  int(20)
  [5]=>
  int(10)
}

Program 2:

PHP

<?php

// Declare a deque
$deck = new \Ds\Deque(["geeks", "for", "geeks", "articles"]);

echo("Elements of Deque\n");

// Display the Deque elements
print_r($deck);

// Reversing the deque
$deck_new = $deck->reversed();
 
echo("\nElements of the reversed deque\n");

// Display the Deque elements
print_r($deck_new);

?>

Output:

Elements of Deque
Ds\Deque Object
(
    [0] => geeks
    [1] => for
    [2] => geeks
    [3] => articles
)

Elements of the reversed deque
Ds\Deque Object
(
    [0] => articles
    [1] => geeks
    [2] => for
    [3] => geeks
)
