จากตัวอย่างการทำตารางเรียน นี้อ่ะครับ ผมต้องการดึงข้อมูลจาก Database ครับ

<?php
include("../db_conn.inc.php");
$selTbTime = "select * from tb_study_time;";
$qryTbTime = mysql_query($selTbTime)or die(mysql_error());
while($rstTbTime = mysql_fetch_assoc($qryTbTime))
{

}
//DATABASE to Array
$selLast = "select TermFull from test_table where ClassID = '".$result["ClassID"]."';";
$qryLast = mysql_query($selLast)or die(mysql_error());
$rstLast = mysql_fetch_assoc($qryLast);//last termfull


$sqlTb = "select * from test_table where ClassID = '".$result["ClassID"]."' and TermFull = '".$rstLast["TermFull"]."' order by DayID asc,TimeIn asc;";
$qryTb = mysql_query($sqlTb)or die(mysql_error());
while($rstTb = mysql_fetch_assoc($qryTb))
{
	$timeTeach[$rstTb['DayID']][] = array( 'time' => $rstTb["TimeIn"]."-".$rstTb["TimeEnd"], 'title' => $rstTb["SubjectID"]." ".$rstTb["SubjectName"]);
