You need to move these conditions

if($cali == $this->today && $this->currentmonth == $this->cMonth && $this->currentyear == $this->cYear){
	$ev = '';
	$ev .= "<td align='center' bgcolor='red' title='Today'>$cali</td>";
}elseif($i <$this->startday){
	$ev = '';
	$ev .= "<td> </td>";
}else{
	$ev = '';
	$ev .= "<td align='center' bgcolor='white'>$cali</td>";
}

outside of the foreach loop so it is

$date = $this->cYear."-".$this->cMonth."-".$cali;
$ev = '';
foreach($this->events as $event){
	if($event['start'] <= $date && $event['end'] >= $date){
		$ev = "<td align='center' bgcolor='#00FF00' title='".$event['description']."'>$cali</td>";
	}
}

if(empty($ev))
{
	if($cali == $this->today && $this->currentmonth == $this->cMonth && $this->currentyear == $this->cYear){
		$ev = "<td align='center' bgcolor='red' title='Today'>$cali</td>";
	}elseif($i <$this->startday){
		$ev = "<td> </td>";
	}else{
		$ev = "<td align='center' bgcolor='white'>$cali</td>";
	}
}

$output .= $ev;

Thank you

[frostdragon]

one last question how can i add a blank td at the end of the the calendar instead of it ending the table after the last day.

[Ch0cu3r]

You need to calculate how many days are leftover.

 

Change

for($i=0; $i<($this->maxday+$this->startday); $i++){

to

$totalDays = $this->maxday+$this->startday; // total days to iterate over
$leftOverDays = ceil($totalDays / 7) * 7 - $totalDays; // days left to iterate over

for($i=0; $i< $totalDays; $i++)

Next change   $output .= '</table>';   to

// add empty table cells to complete calendar
if($leftOverDays > 0) {
	$output .= str_repeat('<td></td>', $leftOverDays);
	$output .= '</tr>';
}

$output .= '</table>';
