PHP Program to Sort an Array in Ascending Order

<?php 

$arr = [5, 2, 8, 3, 1]; 

// Sort array in ascending order 
sort($arr); 

// Display the sorted array 
print_r($arr); 

?>

<?php 

// Associative array 
$arr = ['b' => 5, 'a' => 2, 'd' => 8]; 

// Sort array by values in 
// ascending order 
asort($arr); 

// Display the sorted array 
print_r($arr); 

?>

<?php 

$names = ['John', 'Anna', 'Bob']; 
$ages = [30, 25, 35]; 

// Sorting arrays based on the 
// values in the first array 
array_multisort($names, $ages); 

// Displaying the sorted arrays 
print_r($names); 
print_r($ages); 

?>

<?php 

// Associative array 
$arr = ['b' => 5, 'a' => 2, 'd' => 8]; 

// Sort array using a custom 
// comparison function 
uasort($arr, function ($a, $b) { 
	return $a - $b; 
}); 

// Display sorted array 
print_r($arr); 

?>

<?php
function bubbleSort(array $array) {
    $n = count($array);
    for ($i = 0; $i < $n; $i++) {
        for ($j = 0; $j < $n - $i - 1; $j++) {
            if ($array[$j] > $array[$j + 1]) {
                // Swap the elements
                $temp = $array[$j];
                $array[$j] = $array[$j + 1];
                $array[$j + 1] = $temp;
            }
        }
    }
    return $array;
}

// Define an array
$array = [5, 2, 9, 1, 5, 6];

// Sort the array using Bubble Sort
$sortedArray = bubbleSort($array);

// Print the sorted array
print_r($sortedArray);
?>

<?php
// Example associative array
$array = ['c' => 3, 'a' => 1, 'b' => 2];

// Sort array by keys using ksort()
ksort($array);

print_r($array); // Output: ['a' => 1, 'b' => 2, 'c' => 3]
