Posted it on my blog, but I decided that I should share it here as well, for those of you that need a simple php calendar.

<?php
// This gets today's date
$date = time ();
 
// This puts the day, month, and year in seperate variables
$day  = date('d', $date);
$month= date('m', $date);
$year = date('Y', $date);
 
// Here we generate the first day of the month
$first_day = mktime(0,0,0,$month, 1, $year);
 
//This gets us the month name
$title = date('F', $first_day); 
 
//Here we find out what day of the week the first day of the month falls on
$day_of_week = date('D', $first_day);
 
//Once we know what day of the week it falls on, we know how many blank days occure before it. If the first day of the week is a Sunday then it would be zero
switch($day_of_week) {
  case "Sun": $blank = 0; break;
  case "Mon": $blank = 1; break;
  case "Tue": $blank = 2; break;
  case "Wed": $blank = 3; break;
  case "Thu": $blank = 4; break;
  case "Fri": $blank = 5; break;
  case "Sat": $blank = 6; break;
}
 
// We then determine how many days are in the current month
$days_in_month = cal_days_in_month(0, $month, $year); 
?>
 
<table cellpadding="0" cellspacing="0">
  <tr>
    <th colspan="7"><?php print $month; ?> <?php print $year; ?></th>
  </tr>
  <tr>
    <td>Sun</td>
    <td>Mon</td>
    <td>Tue</td>
    <td>Wed</td>
    <td>Thu</td>
    <td>Fri</td>
    <td>Sat</td>
  </tr>
   <?php $day_count = 1;// This counts the days in the week, up to 7 ?>
  <tr>
  <?php while ($blank > 0): //first we take care of those blank days ?>
    <td>&nbsp;</td> <?php $blank = $blank-1; $day_count++; ?>
  <?php endwhile; ?>
  <?php $day_num = 1; //sets the first day of the month to 1 ?>  
 
  <?php while ($day_num <= $days_in_month): //count up the days, until we've done all of them in the month ?>
    <td><?php print $day_num; ?></td>
    <?php $day_num++; $day_count++; ?>
    <?php if ($day_count > 7): //Make sure we start a new row every week ?> 
  </tr>
  <tr>
    <?php $day_count = 1; ?>
    <?php endif; ?>
  <?php endwhile; ?>
    
  <?php while ($day_count >1 && $day_count <=7): //Finaly we finish out the table with some blank details if needed ?>
    <td>&nbsp;</td>
    <?php $day_count++; ?>
  <?php endwhile; ?>
  </tr>
</table>
