博客日历代码,博客中添加日历的php代码

代码如下：
function calendarnew($starttime = 0) {
global $db, $tablepre, $timestamp, $site_timeoffset, $site_dateformat, $curtime;
 
$starttime = $starttime ? $starttime : $timestamp;
$curtime = gmdate($site_dateformat, $starttime + $timeoffset * 3600);
 
$pendtime = $starttime - (gmdate('j', $starttime + $timeoffset * 3600) - 1) * 86400 - ($starttime + $timeoffset * 3600) % 86400;
$pstarttime = $pendtime - gmdate('t', $pendtime + $timeoffset * 3600 - 1) * 86400;
 
$nstarttime = $pendtime + gmdate('t', $pendtime + $timeoffset * 3600 + 1) * 86400;
$nendtime = $nstarttime + gmdate('t', $nstarttime + $timeoffset * 3600 + 1) * 86400;
 
list($skip, $dim) = explode('-', gmdate('w-t', $pendtime + $timeoffset * 3600 + 1));
$rows = ceil(($skip + $dim) / 7);
 
$blogs = array();
$query = $db->query("SELECT dateline FROM {$tablepre}vitaitems WHERE dateline BETWEEN '$pendtime' AND '$nstarttime'");
while($blog = $db->fetch_array($query)) {
$day = gmdate('j', $blog['dateline'] + $timeoffset * 3600);
!isset($blogs[$day]) ? $blogs[$day] = array('num' => 1, 'dateline' => $blog['dateline'] - $blog['dateline'] % 86400) : $blogs[$day]['num']++;
}
$cal = '';
for($row = 0; $row < $rows; $row++) {
$cal .= '<tr align="center" class="smalltxt">';
for($col = 0; $col < 7; $col++) {
$cur = $row * 7 + $col - $skip + 1;
$curtd = $row * 7 + $col < $skip || $cur > $dim ? '&nbsp;' : $cur;
if(!isset($blogs[$cur])) {
$cal .= '<td>'.$curtd.'</td>';
} else {
$cal .= '<td><a href="blog.php?uid='.$uid.'&starttime='.$blogs[$cur]['dateline'].'&endtime='.($blogs[$cur]['dateline'] + 86400).'" title=" '.$blogs[$cur]['num'].' "><b>'.$cur.'</b></a></td>';
}
}
$cal .= '';
}
return $cal;
