filemtime returns a unix timestamp. you should probably use that format. Alternatively, look into using DateTime PHP class to create date/time objects - these can be compared transparently, and it contains are more reliable inbuilt ways to add/subtract time from a date. — Darragh Enright

You cannot compare dates straight away, but you're on the right track with strtotime. What you need to do is compare both dates in Unix time, and then make sure that they aren't the same date but with different seconds.

$baru = strtotime($tanggal) + (24*3600*$add_days);
$skrg = time();
if ($baru < $skrg && date('Y-m-d', $baru) != date('Y-m-d', $skrg)) {
    // do stuff
}

Try This (only numbers are easy to compare):-

$date1 = strtotime('29-06-2013');
$date2 = strtotime('07-12-2013');

if($date1 < $date2){
    echo "<br/> yes";
}
