How can the natsort() function help in sorting array values in PHP?

When sorting array values in PHP, the default sorting functions may not always produce the desired results, especially when dealing with values that contain numbers in a mixed alphanumeric format. The natsort() function in PHP can be used to sort array values in a natural order, where numbers within the values are sorted based on their numeric value rather than just their string representation.

// Sample array with mixed alphanumeric values
$array = array("item1", "item10", "item2", "item20", "item3");

// Sort the array using natsort()
natsort($array);

// Output the sorted array
print_r($array);
