When in Notepad++ anything in "" inside php in block will not display and finish the table. So the echo "<tr>"; turns grey and does not finish the table. Any suggestions?
<table border='1'>
<tr>
<td><input type='button' value='<' name='previousebutton' onclick="goLastMonth(<?php echo $month.",".$year?>)"></td>
<td colspan='5'> <?php echo $monthName.", ".$year ?> </td>
<td><input type='button' value='>' name='nextbutton'onclick="goNextMonth(<?php echo $month.",".$year?>)" ></td>
</tr>
<tr>
<td width='50px'>Sun</td>
<td width='50px'>Mon</td>
<td width='50px'>Tue</td>
<td width='50px'>Wed</td>
<td width='50px'>Thu</td>
<td width='50px'>Fri</td>
<td width='50px'>Sat</td>
</tr>
<?php
echo "<tr>";
for($i = 1; $i < $numDays+1; $i++ , $counter++){
$timeStamp = strtotime("$year-$month-$i");
if($i == 1) {
$firstDay = date("w", $timeStamp);
for($j = 0; $j < $firstDay; $j++, $counter++) {
echo "<td>$nbsp;</td>";
}
}
if($counter % 7 == 0) {
echo "</tr><tr>";
}
}
echo "</tr>";
?>
</table>

Answer 1

Modified some of your code:
<?php
if(isset($_GET['day'])){ $day = $_GET['day']; }else{ $day = date("j"); }
if(isset($_GET['month'])){ $month = $_GET['month']; }else{ $month = date("n"); }
if(isset($_GET['year'])){ $year = $_GET['year']; }else{ $year = date("Y"); }
//calender variable
$currentTimeStamp = strtotime("$year-$month-$day");
$monthName = date("F", $currentTimeStamp);
$numDays = date("t" , $currentTimeStamp);
$counter = 1;
$day = date('d', $currentTimeStamp);
$firstDay = date('w', strtotime("{$year}-{$month}-01"));
?>
<table border='1'>
<tr>
<td><input type='button' value='<' name='previousebutton' onclick="goLastMonth(<?php echo $month.",".$year?>)"></td>
<td colspan='5'> <?php echo $monthName.", ".$year ?> </td>
<td><input type='button' value='>' name='nextbutton'onclick="goNextMonth(<?php echo $month.",".$year?>)" ></td>
</tr>
<tr>
<td width='50px'>Sun</td>
<td width='50px'>Mon</td>
<td width='50px'>Tue</td>
<td width='50px'>Wed</td>
<td width='50px'>Thu</td>
<td width='50px'>Fri</td>
<td width='50px'>Sat</td>
</tr>
<tr>
<?php for($i = 0; $i < $firstDay; $i++): ?>
<td></td>
<?php endfor; ?>
<?php for($i = 1; $i <= $numDays; $i++): ?>
<?php if($day == $i): ?>
<td><strong><?php echo $i ?></strong></td>
<?php else: ?>
<td><?php echo $i ?></td>
<?php endif; ?>
<?php if(($i + $firstDay) % 7 == 0): ?>
</tr><tr>
<?php endif; ?>
<?php endfor; ?>
<?php for($i = 0; ($i + $firstDay + $numDays) % 7 != 0; $i++): ?>
<td></td>
<?php endfor; ?>
</tr>
</table>

Answer 2

You can try to use the alternate control structure syntax for this, although (in my opinion) it can make some code harder to read:
<?php for($i = 1; $i < $numDays+1; $i++ , $counter++){
$timeStamp = strtotime("$year-$month-$i");
if($i == 1) {
$firstDay = date("w", $timeStamp);
for($j = 0; $j < $firstDay; $j++, $counter++): ?>
<td>$nbsp;</td>
<?php endfor; ?>
}
if($counter % 7 == 0): ?>
</tr><tr>
<?php endif; ?>
}
?>
