php - 检查当前日期是否在假期日期范围内

Question

如何检查当前日期是否在假期日期范围内？我有一个表“假期”，其中有两个日期列:开始日期和结束日期。用户可以定义该范围内的假期日期。我需要创建一个循环来检查当前日期是否在假日日期范围内，如果是，则当前日期变为“+1 天”，然后再次检查。到目前为止我已经做到了:

<?php
include ("config.php");
$curdate = date('Y-m-d', time());
$res = mysql_query("SELECT * FROM holidays WHERE '$curdate' BETWEEN `start_date` and `end_date`");
$resu = mysql_num_rows($res);
 if ($resu == NULL)
      {
      echo "Date is not range";
      }
 else
    {
    echo "Date is in range";
    }
?>

你不需要有一个循环，所以你可以这样做

<?php
   include ("config.php");
   $curdate = date('Y-m-d', time());
   $res = mysql_query("SELECT id FROM holidays WHERE '$curdate' BETWEEN `start_date` and `end_date`");
   $resu = mysql_num_rows($res);
   if ($resu == 0)
   {
      echo "Date is not range";
   }
   else
   {
      $res = mysql_query("SELECT end_date FROM holidays WHERE end_date > '$curdate' ORDER BY end_date ASC LIMIT 1");
      $resu = mysql_fetch_array($res);

      $next_day = strtotime($resu['end_date']) + 24 * 60 * 60;
      echo 'The next available day is ' . date("Y-m-d", $next_day);
   }
?>
