<?

	$result = mysql_query($sql);
	mysql_query("set NAMES tis620");
	$sql = "select * from food;";
	$result = mysql_query($sql);
	echo "<table border=1>
				<tr>
					<td>เมนู</td>
					<td>รายการอาหาร</td>
					<td>ราคา</td>
					<td>Aciton</td>
				</tr>";
	while ($dbarr = mysql_fetch_array($result))
	{
		echo "<tr>
				<td>$dbarr[order]</td>
				<td>$dbarr[list]</td>
				<td>$dbarr[price]</td>
				<td><a href=delete2.php?id=$dbarr[order]>ลบ</a>
				<a href=updateload2.php?id=$dbarr[order]>แก้ไข</a></td>
