Question

我想知道unix时间戳是什么日子。例如，1322784000应该告诉我此时间戳是First Friday，其中1326989000将返回Third Thursday。我不知道从哪里开始，以前有人做过这样的事情，可以帮我一把。

Answer 1

您可以使用此代码来确定：

$ts=array(1322784000, 1326989000, 1323216000, strtotime('2011-12-28'), strtotime('2011-12-21'), strtotime('2011-12-28'), strtotime('2011-12-29') );
foreach ($ts as $t) {
   $dt = new DateTime('@' . $t);
   $d = ceil($dt->format('d')/7);
   $str="";
   switch ($d) {
      case 1: $str = "1st ";
         break;
      case 2: $str = "2nd ";
         break;
      case 3: $str = "3rd ";
         break;
      case 4: $str = "4th ";
         break;
      default: $str = "5th ";
         break;
   }
   echo $dt->format('Y-m-d H:i:s') . " is: " . $str . $dt->format('l') . "\n";
}

<强>输出

2011-12-02 00:00:00 is: 1st Friday
2012-01-19 16:03:20 is: 3rd Thursday
2011-12-07 00:00:00 is: 1st Wednesday
2011-12-28 00:00:00 is: 4th Wednesday
2011-12-21 00:00:00 is: 3rd Wednesday
2011-12-28 00:00:00 is: 4th Wednesday
2011-12-29 00:00:00 is: 5th Thursday
