Echo out SQL result to create a timetable - php

Question

I am having problems printing out a timetable using the results from a SQL statement and some HTML layout with PHP.
I have the times of the classes along the top of the page.
I am trying to put the days of the week along the side of the page and then check if the result of the SQL statement (containing a module) should be printed in the specific day and time.
//Print out the top of the array to display the times
echo "<div><table class='table table-bordered'><thead><tr><th></th><th>9-10</th><th>10-11</th><th>11-12</th><th>12-13</th><th>13-14</th><th>14-15</th><th>15-16</th><th>16-17</th></tr></thead><tbody>'";
//Now loop through the result of the SQL statement that contains the modules associated with the selected course
while($row = mysqli_fetch_array($result1)) {
for($d = 1; $d < 6; $d++){
$printday = $days[$d];
echo "$printday";
for($t = 9; $t < 17; $t++) {
if($row['Day'] == $d && $row['Time'] == $t){ //fix this area so that it moves along
echo "<td>" . $row['ModuleName'] . "<br/>\n " .$row['Location'] . "</td>";
} //if
else {
echo "<td></td>";
} //else
} //for 2
echo "</tr>";
} //for 1
} //while
The problem is that I am printing out Monday-Friday 3 times as there are 3 $row results. Any idea how I could get this to work.

Your looping through your data in the wrong spot, you first need to put that in an array so you can loop through it for each day/time.
//Print out the top of the array to display the times
echo "<div><table class='table table-bordered'><thead><tr><th>Day</th><th>9-10</th><th>10-11</th><th>11-12</th><th>12-13</th><th>13-14</th><th>14-15</th><th>15-16</th><th>16-17</th></tr></thead><tbody>'";
//Now loop through the result of the SQL statement that contains the modules associated with the selected course
$courses = array();
while($row = mysqli_fetch_array($result1)) {
$courses[] = $row;
} //while
for($d = 1; $d < 6; $d++){
$printday = $days[$d];
echo "<tr><td>" . $printday . "</td>";
for($t = 9; $t < 17; $t++) {
unset($course_row);
foreach($courses as $course){
if($course['Day'] == $d && $course['Time'] == $t){ //fix this area so that it moves along
$course_row .= $course['ModuleName'] . "<br/>\n " .$course['Location'] . "<br/>\n<br/>\n";
} //if
}
if(isset($course_row)){
echo "<td>" . $course_row . "</td>";
} else {
echo "<td> </td>";
} //else
} //for 2
echo "</tr>";
} //for 1
