query in php while loop firing but giving results of one variable - php

Question

i have a timetable application which needs to generate timetables for all teachers in one go based on the semester. i am querying teacher id(s) and inside the while loop i am using the same code used to generate an individual teacher's timetable. according to mysql logs, query is firing for every teacher id but same timetable is being generated for all teachers.
i checked every line of code but its somehow not working.
I am so stuck on this, please help.
my php code:
<?php
include ("includes/functions.php");
$timespan = mysql_real_escape_string($_GET['timespan']);
$q11 = "select * from teachers order by teacher";
$r11 = mysql_query($q11) or die(mysql_error());
while($rows11 = mysql_fetch_array($r11)){
$teacher = $rows11['id'];
$array_day=array('Mon' => 0, 'Tue' => 1, 'Wed' => 2, 'Thu' => 3, 'Fri' => 4, 'Sat' => 5);
if($timespan=="BS"){

edited code snippet:
while($toRepeat==1){
while($rows = mysql_fetch_array($r1)){
$data[] = $rows; // creating multidimensional array
$dt = $data[$rowToProcess]['day'];
$period = $data[$rowToProcess]['period'];
$paper = $data[$rowToProcess]['p_s'];
$course = $data[$rowToProcess]['c_s'];
$room = $data[$rowToProcess]['room'];
$class = $data[$rowToProcess]['class'];
$id = $data[$rowToProcess]['id'];
$part = $data[$rowToProcess]['part'];
$subgroup = $data[$rowToProcess]['sub_group'];
$weekselector = $data[$rowToProcess]['filter'];
$egstatus = $data[$rowToProcess]['egstat'];
}
and the output afterwards.

You need to create another while loop while ($rows = mysql_fetch_array($r1)) { } You currently don't have this in a loop thus the repeating value.
Take this out of the loop:
$array_day=array('Mon' => 0, 'Tue' => 1, 'Wed' => 2, 'Thu' => 3, 'Fri' => 4, 'Sat' => 5);
I am not quite sure what you are asking. What do you mean it results of only one variable. Do you mean the first variable in the loop is the only one being returned correctly or on the second loop no variables are being returned correctly?
