A sort function to sort elements by a reference order.

usort($array_to_sort, function($a, $b) use ($reference_array) {
$pos_a = array_search($a, $reference_array);
$pos_b = array_search($b, $reference_array);
return $pos_a - $pos_b;
});
return $array_to_sort;
}
// Example usage
$reference_array = ["one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten"];
$array_to_sort = ["three", "one", "seven", "four", "ten"];
$sorted_array = sort_by_reference($array_to_sort, $reference_array);
// Print the result to verify the sorting
print_r($sorted_array);
