Bubble Sort - Exchange Sort PHP

Bubble sort is a simple sorting algorithm that gradually moves the largest elements to the end of the list by repeatedly exchanging adjacent elements. The name of this sorting algorithm comes from the fact that larger elements will slowly "float" to the top of the array through exchange, hence the name bubble sort.

The following is the code to implement bubble sort using PHP:

function bubbleSort($arr) {
   
    
    
    $n = count($arr);

    for ($i = 0;
