PHP Ds\Deque::set() Function


Hello dear readers! welcome back to another edition of our tutorial on PHP. In this tutorial guide, we are going to be discussing about the PHP Ds Deque set() Function.

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

Syntax

Following below is the syntax to use this function -

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


Return Value

This built-in PHP function does not return any value. This throws an OutOfRangeException if an index is not valid.

Example1

Try out the below example -

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

Example2

Try the following example -

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