Sort an array of integers without using PHP built-in sort functions OR Bubble Sort

Today, I want to show you guys how to sort an array of integers without using PHP built-in sort function. It can be done using different sorting algorithms. Here in this post I have used Bubble Sort algorithm.

<?php
$srtArray=array(2,8,9,5,6,3,7,5,8,4,1);
 for ($i=0; $i<count($srtArray); $i++) {
    for ($j=0; $j<count($srtArray); $j++) {
      // Compare two elements of array
      if ($srtArray[$j] > $srtArray[$i]){
        $tmp = $srtArray[$i];
        $srtArray[$i] = $srtArray[$j];
        $srtArray[$j] = $tmp;
      }
    }
 }
//Print an array after sorting
 for($i=0;$i<count($srtArray);$i++){
   echo $srtArray[$i]."<br>\n";
 }

 ?>
