How can array indexes be sorted based on their values in PHP?

To sort array indexes based on their values in PHP, you can use the `asort()` function. This function will sort the array by values while maintaining the association between keys and values. Once the array is sorted, the indexes will be rearranged based on the sorted values. 

$array = array("b" => 4, "a" => 2, "c" => 6);
asort($array);
print_r($array);
