	$strStartDate = "2015-03-02";
	$strEndDate = "";
	$i = 0;
	$i2 = 10;
	$intHoliday = 0;
	$intTotalDay = ((strtotime($strEndDate) - strtotime($strStartDate))/  ( 60 * 60 * 24 )) + 1; 

	while ($i < $i2 ) {
		
		$DayOfWeek = date("w", strtotime($strStartDate));
		if($DayOfWeek == 1 or $DayOfWeek == 3 or $DayOfWeek == 5)  // 0 = Sunday, 6 = Saturday;
		{
			$i++;
			echo "$strStartDate = <font color=red>เรียน</font><br>";
			include 'connect.php';
			$sql = "UPDATE tbtestday
			SET schedule = ',$strStartDate' WHERE test_id LIKE '1'"; 
			$query = mysql_query($sql) or die(mysql_error());
		}
		else

	}
	
	echo "<hr>";
	include 'connect.php';
	$sql1= "SELECT * FROM tbtestday WHERE test_id LIKE '1' ";
	echo "<br>$schedule<br>";
	echo  $Enddate = $strStartDate = date ("Y-m-d", strtotime("-1 day", strtotime($strStartDate)));
	$result = mysql_query($sql1);
	$sql = "UPDATE tbtestday
