PHP undefined offset (not an error) try catch - php

Question

I would like to list (upto) six of the remaining assignments due for the acedemic year onto a webpage.
The data for the remaining assignments comes from a mysql db.
When there are six or more assignments left, the webpage displays the info correctly.
If there are less than six left, then i get a undefined offset error (and i understand why).
Basically, i am trying to programmatically ignore the offset error.
I've tried looking and the following:
try/catches in the php.
tried using (in the foreach loop)
if($row['name'] == null){$row['name'] = "";}
etc.
index.php
include('getdata.php');
$nextAssArray0 = getNextAssessments($courseInfoArray[0], 0);
$nextAssArray1 = getNextAssessments($courseInfoArray[0], 1);
$nextAssArray2 = getNextAssessments($courseInfoArray[0], 2);
$nextAssArray3 = getNextAssessments($courseInfoArray[0], 3);
$nextAssArray4 = getNextAssessments($courseInfoArray[0], 4);
$nextAssArray5 = getNextAssessments($courseInfoArray[0], 5);
<div class="col-sm-4">
<h3>You have <?php echo '' ?> assignments left</h3>
<p>Assignment: <?php echo $nextAssArray0[0]; ?> is due on <?php echo $nextAssArray0[1]; ?></p>
<p>Assignment: <?php echo $nextAssArray1[0]; ?> is due on <?php echo $nextAssArray1[1]; ?></p>
<p>Assignment: <?php echo $nextAssArray2[0]; ?> is due on <?php echo $nextAssArray2[1]; ?></p>
<p>Assignment: <?php echo $nextAssArray3[0]; ?> is due on <?php echo $nextAssArray3[1]; ?></p>
<p>Assignment: <?php echo $nextAssArray4[0]; ?> is due on <?php echo $nextAssArray4[1]; ?></p>
<p>Assignment: <?php echo $nextAssArray5[0]; ?> is due on <?php echo $nextAssArray5[1]; ?>
</p>
</div>
getdata.php
function getNextAssessments($courseID, $offset)
{
try
{
include('dbconn.php');
$array = array();
$stm = $conn->prepare("CALL getUpcomingAssignments(:courseID, :offset)");
$stm->bindParam(':courseID', $courseID);
$stm->bindParam(':offset', $offset);
$stm->execute();
foreach ($stm->fetchALL() as $row)
{
array_push($array, $row['name']);
array_push($array, $row['due_date']);
array_push($array, $row['tem']);
}
}
catch (Exception $e)
{
$array = array('','','');
}
return $array;
}
I am after the following functionality:
1) if there is only three assignments left - then only three display.
2) if there is ten assignments left - then only six are displayed.
3) if there are no assignments left - then nothing is displayed in those

First of all, it is not a good idea to make SQL query for every database record. Remove limit from query, and put all your assesments in array. Then do something like this:
<h3>You have <?php echo count($assesments) ?> assignments left</h3>
<?php
foreach($assesments as $assesment){
echo "<p>Assignment: {$assesment[0]} is due on {$assesment[1]} ?></p>"
}
?>
Also I would recommend changing your code so you have array like $assesment['dueDate'] instead of $assesment[1].
