    Can using the date cause problems for date comparison?

    Here's the code.

    $link="http://xbox360cheat.or g";

    $close_date=$_P OST["close_date "]; #last content change check

    if ($close_date == 0)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m"), date
    ("d")+7, date("Y")));
    else if ($close_date == 1)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m"), date
    ("d")+5, date("Y")));
    else if ($close_date == 2)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m"), date
    ("d")+3, date("Y")));
    else if ($close_date == 3)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m"), date
    ("d")+14, date("Y")));
    else if ($close_date == 4)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m"), date
    ("d")+21, date("Y")));
    else if ($close_date == 5)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m")+1, date
    ("d"), date("Y")));
    else if ($close_date == 6)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m")+2, date
    ("d"), date("Y")));
    else if ($close_date == 7)
    $close_date = date("Y-m-d H:m:s", mktime(12, 0, 0, date("m")+3, date
    ("d"), date("Y")));

    $linkStatus=che ckDate($link,$c lose_date);

    Could the close_date be one that is not the expected value? For example,
    if the month is 11 and $close_date == 7, then the mktime function should
    return the next year for the year value, not the current year. And if the
    day is the last week of December, than the month and year should change
    if close_date == 7. Thanks for any help.

      According to the manual, mktime() will return false if the arguments
      are invalid.

      You can avoid such problems altogether by just using strtotime(). It
      also makes what you're trying to do clearer:

      switch($close_d ate) {
      case 0:
      $close_date = strtotime('+7 days');
      break;
      case 1:
      $close_date = strtotime('+5 days');
      break;
      case 2:
      $close_date = strtotime('+3 days');
      break;
      case 3:
      $close_date = strtotime('+2 weeks');
      break;
      case 4:
      $close_date = strtotime('+3 weeks');
      break;
      case 5:
      $close_date = strtotime('+1 month');
      break;
      case 6:
      $close_date = strtotime('+2 months');
      break;
      case 7:
      $close_date = strtotime('+3 months');
      break;
      }

      //Make it noon on that day:
      $close_date = mktime(12, 0, 0, date('m', $close_date), date('d',
      $close_date), date('Y', $close_date));
      //Format it:
      $close_date = date('Y-m-d H:m:s', $close_date);

              Admittedly, this is very legible and correct.
              Less obvious but short:

              $dateopts=array ('+7 days','+5 days','+3 days','+2 weeks',
              '+3 weeks','+1 month','+2 months','+3 months');
              $close_date= strtotime ($dateopts[$close_date]);

              Sh.
