The PHP asort() and arsort() functions can be used for sorting an array by value. The following section will show you how these functions basically work.

Sorting Associative Arrays in Ascending Order

You can use the asort() function for sorting an associative array by value alphabetically in the ascending order, while maintaining the relationship between key and data.

<?php
$fruits = array("b"=>"banana", "a"=>"apple", "d"=>"dog", "c"=>"cat");
 
// Sorting the array by value
asort($fruits);
print_r($fruits);
?>

You can use the arsort() function for ssorting an associative array by value alphabetically in the descending order, while maintaining the relationship between key and data.

<?php
$fruits = array("b"=>"banana", "a"=>"apple", "d"=>"dog", "c"=>"cat");
 
// Sorting the array by value
arsort($fruits);
print_r($fruits);
?>
