write sort without srot in php

can help with that. Sorting an array without using PHP's built-in sorting functions involves implementing a sorting algorithm manually. One of the simplest sorting algorithms is the Bubble Sort algorithm. Here's an example of how you can sort a single-dimensional indexed array containing integers without using PHP's sorting functions:

php
<?php
function bubbleSort(&$arr) {
    $n = count($arr);
    for ($i = 0; $i < $n - 1; $i++) {
        // Last $i elements are already in place
        for ($j = 0; $j < $n - $i - 1; $j++) {
            if ($arr[$j] > $arr[$j + 1]) {
                // Swap elements if they are in the wrong order
                $temp = $arr[$j];
                $arr[$j] = $arr[$j + 1];
                $arr[$j + 1] = $temp;
            }
        }
    }
}

// Sample array
$array = [5, 3, 8, 1, 9, 2];

// Sort the array using bubble sort
bubbleSort($array);

// Print the sorted array
foreach ($array as $value) {
    echo $value . " ";
}
?>

This program defines a function bubbleSort that implements the Bubble Sort algorithm. It then uses this function to sort the given array. The sorted array is printed using a loop.

Keep in mind that Bubble Sort is not the most efficient sorting algorithm for large arrays, as it has a time complexity of O(n^2). However, it's suitable for educational purposes and small arrays. For larger arrays, you might consider more efficient sorting algorithms like Quick Sort or Merge Sort.
