Example 1

The following program demonstrates the usage of the PHP Ds\Deque::toArray() function −

<?php
   $deque = new \Ds\Deque([36, 18, 9, 27, 45]);
   echo "The deque elements are: \n";
   print_r($deque);
   echo "An array elements are: \n";
   print_r($deque->toArray());
?>

Output

After executing the above program, it will display the following output −

The deque elements are:
Ds\Deque Object
(
    [0] => 36
    [1] => 18
    [2] => 9
    [3] => 27
    [4] => 45

Example 2

Following is an example of the PHP Ds\Deque::toArray() function. This function is used to retrieve an array containing all elements of the deque (['b', 'd', 'h', 'k', 'l', 't']) −

<?php
   $deque = new \Ds\Deque(['b', 'd', 'h', 'k', 'l', 't']);
   echo "The deque elements are: \n";
   print_r($deque);
   echo "The array elements are: \n";
   print_r($deque->toArray());
?>

Output

The above program generates the following output −

The deque elements are:
Ds\Deque Object
(
    [0] => b
    [1] => d
    [2] => h
    [3] => k
    [4] => l
    [5] => t
)
The array elements are:
Array
(
    [0] => b
    [1] => d
    [2] => h
    [3] => k
    [4] => l
    [5] => t
