How can PHP beginners effectively sort data sets by date without complicating the code?

When sorting data sets by date in PHP, beginners can effectively use the `usort()` function along with a custom comparison function. This allows for sorting an array of dates in ascending or descending order without complicating the code. 

// Sample data set of dates
$dates = ['2022-03-15', '2022-01-20', '2022-05-10'];

// Custom comparison function for sorting dates
function cmp($a, $b) {
    return strtotime($a) - strtotime($b);
}

// Sort the dates array in ascending order
usort($dates, 'cmp');

// Output sorted dates
print_r($dates);
