sql="select ซ้อน select ทำยังไงให้ข้อมูลแสดงคนละอย่างครับ

	 $rs = mysql_query("SELECT * FROM table1 , table2 WHERE table1.id = table2.pass_id");
	 $temp = "";
	 while($rows = mysql_fetch_array($rs))
	 {
		 if($rows[0] != $temp)
		 {
			 $temp = $rows[0];
			 echo $rows[0]."<br/>";
		 }
		 if($temp == $rows[4])
		 {
			 echo $rows[3]."<br/>";
		 }
		 
	 }

$sql = "select * from groups inner join menu where groups.id_pass = menu.id_pass";

<?php


$rs_group = mysql_query("SELECT * FROM groups");

while($row_group = mysql_fetch_array($rs_group))
{

	$rs_menu = mysql_query("SELECT * FROM menu WHERE id_pass = ".$row_group['id_pass']."");

	while($row_menu = mysql_fetch_array($rs_menu))
	{
	
	 	echo $row_menu['menu_name'];
	 
	}
 
}
