检查当前日期是否在假期日期范围内

Question

How to check if current date falls in holiday date range? I have a table "holidays" with two DATE columns, start_date and end_date. Users can define holidays dates in that range. I need to make a loop that checks is the current date within the holiday date range, and if it is, the current date goes "+1 day", and checks again. I've made it so far:

<?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";
    }
?>

You don't need to have a loop, so you can do it like this

<?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);
   }
?>
