What PHP function is suggested in the forum thread to sort the array of folder names based on dates?

The issue at hand is sorting an array of folder names based on dates in PHP. One suggested solution in the forum thread is to use the `usort()` function along with a custom comparison function that extracts the date from each folder name and compares them. This allows for sorting the array in ascending or descending order based on the dates embedded in the folder names.

// Function to compare two folder names based on dates
function compareFolderDates($a, $b) {
    $dateA = strtotime(substr($a, 0, 10));
    $dateB = strtotime(substr($b, 0, 10));
    
    if ($dateA == $dateB) {
        return 0;
    }
    return ($dateA < $dateB) ? -1 : 1;
}

// Sort the array of folder names based on dates
usort($folderNames, 'compareFolderDates');
