This PHP checks booked dates in the database.
<?php

$result = mysqli_query($this->con,$sql);
while($row=mysqli_fetch_array($result))
{
$thisBooking = $row['date'];
$thisBookingDateTime = new DateTime($thisBooking);
array_push($this->bookings,$thisBookingDateTime);
}
return $this->bookings;
}

Answer 2

I think your problem is that is that you need to put the format in order to compare two Datetime :
if ($thisDate->format('Y-m-d')==$bookingDate->format('Y-m-d'))
{
echo "Booked";
....
}

Answer 3

In addition to #SimonGuichard's answer, I suggest that you return an associative array from the getMonthlyBookings function that contains both the date and the activityTitle. This way, you wouldn't have to select the title from the database again when it needs to be displayed.
public function getMonthlyBookings($thisMonth,$thisYear) {
$sql = "SELECT date,activityTitle FROM activityEvent WHERE YEAR(date) = $thisYear AND MONTH(date) = $thisMonth";
$result = mysqli_query($this->con,$sql);
while($row=mysqli_fetch_array($result)) {
$this->bookings[] = array('date'=>new DateTime($row['date']), 'activityTitle'=>$row['activityTitle']);
}
return $this->bookings;
}
Then in the script that displays the calendar, you should modify it this way:
$day = $i - $startday + 1;
$thisDate = new DateTime("$cYear-$cMonth-$day");
$jsEvent[] = "document.getElementById('trigger" . $i . "').onclick = function() {showForm()};";
echo "<td align='center' valign='middle' height='20px'><a href='#' id='trigger" . $i . "'>". ($i - $startday + 1) . "</a>";
// $bookings is an associative array of the form array('0'=>array('date'=>'date_value', 'activityTitle'=>'activityTitle_value'))
foreach ($bookings as $key => $value) {
if ($thisDate->format('Y-m-d') === $value['date']->format('Y-m-d')) {
// this prints out the activity title
echo $value['activityTitle'];
}
}
