PHP Ds\Deque::set() Function

Hello folks! welcome back to a new edition of our tutorial on PHP. In this tutorial guide, we are going to be studying about the PHP Ds Deque set() Function.

The built-in PHP Ds Deque set() function updates the value at a given index.


Following below is the syntax to use this function -

public void Ds\Deque::set( int $index , mixed $value )

Return Value

This function does not return any value. It throws an OutOfRangeException if an index is not valid.


Try out the below example -

   $deque = new \Ds\Deque([1, 2, 3, 4, 5]); 
   echo("The elements in deque: \n"); 
   $deque->set(4, 10); 
   echo("The deque after setting value at index 2: \n"); 


Try the following example -

   $deque = new \Ds\Deque(["Web", "Design", "Tutorialz", "Nigeria"]); 
   echo("The elements of deque: \n"); 
   $deque->set(2, "webdesigntutorialz"); 
   echo("The deque after setting value at index 2: \n");
