DateTime supports microseconds since 5.2.2. This is mentioned in the documentation for the date function, but bears repeating here. You can create a DateTime with fractional seconds and retrieve that value using the 'u' format string.

format('u'); // 012345

// Output the date with microseconds.
echo $d->format('Y-m-d\TH:i:s.u'); // 2011-01-01T15:03:01.012345

// Unix Format
echo "
d2: ". $d->format('U.u');

function get_data_unix_ms($data){
    $d = new DateTime($data);
    $new_data = $d->format('U.u');
    return $new_data;
}

function get_date_diff_ms($date1, $date2)
    {
        $d1 = new DateTime($date1);
        $new_d1 = $d1->format('U.u');

        $d2 = new DateTime($date2);
        $new_d2 = $d2->format('U.u');

        $diff = abs($new_d1 - $new_d2);

        return $diff;
    }
