Build table with rowspan using multidimensional array - php

Question

I want students and events for week to be displayed in calendar format.I have this array as follows. Every student has 7 arrays starting from monday to sunday and inner array of each has events for day
$array = [
'Alex' => [
[
['event' => 'eventName1'],['event' => 'eventName2']
],
[
['event' => 'eventName3'],['event' => 'eventName4']
],
[
['event' => 'eventName5'],['event' => 'eventName6']
],
[
['event' => 'eventName7'],['event' => 'eventName8']
],
[],
[],
[]
],
'Allen' => [
[
['event' => 'eventName'],['event' => 'eventName']
],[
['event' => 'eventName'],['event' => 'eventName']
],
[],
[],
[],
[],
[]
],
];
I need the array to displayed as week calendar,
I don't know where it gone wrong with following code
<table>
<thead>
<tr>
<th>Participant</th>
<th>Monday</th>
<th>Tuesday</th>
<th>Wednesday</th>
<th>Thrusday</th>
<th>Friday</th>
<th>Satday</th>
<th>Sunday</th>
</tr>
</thead>
<tbody>
<?php foreach ($array as $participant => $event): ?>
<?php foreach ($event as $i => $value):?>
<tr>
<?php if ($i === 0): ?>
<td rowspan="2"><?= $participant ?></td>
<?php endif ?>
<?php foreach ($value as $index => $eventD):?>
<td><?php echo $eventD['event']; ?></td>
</tr>
<?php endforeach ?>
<?php endforeach ?>
<?php endforeach ?>
</tbody>
</table>
My problem is the loop and how to print the the events of the particular day.
Can anyone please in building the correct format. thanks for help

Try like this if my understanding is correct
<?php
$array = [
'Alex' => [
[
['event' => 'eventName1'],['event' => 'eventName2']
],
[
['event' => 'eventName3'],['event' => 'eventName4']
],
[
['event' => 'eventName5'],['event' => 'eventName6']
],
[
['event' => 'eventName7'],['event' => 'eventName8']
],
[],
[],
[]
],
'Allen' => [
[
['event' => 'eventName'],['event' => 'eventName']
],[
['event' => 'eventName'],['event' => 'eventName']
],
[],
[],
[],
[],
[]
],
];
echo "<table border='1'>
<thead>
<tr>
<th>Participant</th>
<th>Monday</th>
<th>Tuesday</th>
<th>Wednesday</th>
<th>Thrusday</th>
<th>Friday</th>
<th>Satday</th>
<th>Sunday</th>
</tr>
</thead>
<tbody>";
foreach($array as $key => $data)
{
echo "<tr>
<td>$key</td>";
foreach($data as $data2) {
if(is_array($data2) && isset($data2[0])) {
echo "<td>";
array_walk($data2, function($val, &$dat){
echo $val['event'].', ';
});
echo "</td>";
} else {
echo "<td></td>";
}
}
echo "</tr>";
}
echo "</tbody>
</table>";
?>
