PHP Array Exercises : Sort an associative array by values

PHP Array: Exercise-34 with Solution

Write a PHP program to sort an associative array (alphanumeric with case-sensitive data) by values.

Sample Solution:

PHP Code:

<?php
// Define an associative array with string keys and values
$test_array = array(
    0 => 'example1',
    1 => 'Example11',
    2 => 'example10',
    3 => 'Example6',
    4 => 'example4',
    5 => 'EXAMPLE40',
    6 => 'example10'
);

// Sort the array maintaining index association, using a case-insensitive natural order sort
asort($test_array, SORT_STRING | SORT_FLAG_CASE | SORT_NATURAL);

// Display the sorted array using print_r
print_r($test_array);
?>

Output:

Array                                                       
(                                                           
    [0] => example1                                         
    [4] => example4                                         
    [3] => Example6                                         
    [2] => example10                                        
    [6] => example10                                        
    [1] => Example11                                        
    [5] => EXAMPLE40                                        
)
