<th style="min-width:20%;"><strong>Sat</strong></th>
</tr>
<?php
$today = getdate();
$timestamp = mktime(0, 0, 0, $cMonth, 1, $cYear);
$maxday = date("t", $timestamp);
$thismonth = getdate($timestamp);
$startday = $thismonth['wday'];
for ($i = 0; $i < ($maxday + $startday); $i++)
{
if (($i % 7) == 0)
echo "<tr height='50px'>";
if ($i < $startday) {
echo "<td class='invalid'></td>";
}
else {
$thisdate = ($i - $startday + 1)."-".$thismonth['mon']."-".$thismonth['year'];
$thisdate = strtotime($thisdate);
if($thisdate<=time()) {
if(isset($attendance[$thisdate]) && $attendance[$thisdate]=="Present")
{
echo "<td class='Present'>";
}
else
{
echo "<td class='absent'>";
}
?>
<b><span style="padding-left:2px"><?php echo $i - $startday + 1; ?></span></b>
</div></td>
<?php } else { ?>
<td class="otherdate"><span style="padding-left:2px"><b>{$i - $startday + 1}</b></span> </td>
<?php

<?php
if (isset($_GET['ym'])) {
$ym = $_GET['ym'];
}else{
$ym = date('Y-m');
}
$timestamp = strtotime($ym,"-01");
if ($timestamp === false) {
$timestamp = time();
}
// today
$today = date('Y-m-d', time());
// h3 title
$html_title = date('Y / F',$timestamp);
$prev = date('Y-m', mktime(0,0,0,date('m', $timestamp)-1,1, date('Y', $timestamp)));
$next = date('Y-m', mktime(0,0,0,date('m', $timestamp)+1,1, date('Y', $timestamp)));
// days numbers
$day_count = date('t', $timestamp);
$str = date('w', mktime(0,0,0,date('m', $timestamp),1, date('Y', $timestamp)));
// creating calander
$weeks = array();
$week = '';
$week .= str_repeat('<td style="background-color: gray"></td>', $str);
for ($day=1; $day <= $day_count ; $day++, $str++) {
$date = $ym.'-'.$day;
if ($today == $date) {
$week .= '<td class="today" style="vertical-align: middle;"><span>'.$day.'</span>';
}else{
$week .= '<td style="vertical-align: middle;">'.$day;
}
$week .= '</td>';
if ($str % 7 == 6 || $day == $day_count) {
if ($day == $day_count) {
$week .= str_repeat('<td style="background-color:gray"></td>',6 -($str % 7));
}
$weeks[] = '<tr>'.$week.'</tr>';
$week = '';
}
}
foreach ($weeks as $week) {
echo $week;
}
?>
