php時間函數，即拿即用

• 時間差函數

function tranTime($time){    $rtime = date("m-d H:i", $time);    $htime = date("H:i", $time);    $time = time() - $time;    if ($time < 60) {        $str = '剛剛';    } elseif ($time < 60 * 60) {        $min = floor($time / 60);        $str = $min . '分鐘前';    } elseif ($time < 60 * 60 * 24) {        $h = floor($time / (60 * 60));        $str = $h . '小時前 ' . $htime;    } elseif ($time < 60 * 60 * 24 * 3) {        $d = floor($time / (60 * 60 * 24));        if ($d == 1)            $str = '昨天 ' . $rtime;        else            $str = '前天 ' . $rtime;    } else {        $str = $rtime;    }    return $str;}

• 倒計時天數小時分秒函數

function get_countdown($unix_time = '')  {    if (empty($unix_time)) return false;    if ($unix_time < time()) return array("day" => 0, "hour" => 0, "min" => 0, "sec" => 0);    $timediff = $unix_time - time();    $days = intval($timediff / 86400); // 時間差算整天數    $remain = $timediff % 86400;       //整除天數取餘,餘下來秒數 記作 A    $hours = intval($remain / 3600);   // 用A除3600 算整小時數    $remain = $remain % 3600;          //用A整除小時取餘數 記作B    $mins = intval($remain / 60);      // 用B除60算整分數    $secs = $remain % 60;              // 用B整數分取餘數 為剩下的秒數    $res = array("day" => $days, "hour" => $hours, "min" => $mins, "sec" => $secs);    return $res;  }
