博客日历问题的PHP实现Calendar函数

下面是实现的代码,忘记从哪里扒下来的了,极大的可能是Discuz!的个人空间里面

现在贴出来给大家共享

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" >';

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 {

$cal .= '<td><a href="blog.php?u&starttime='.$blogs[$cur]['dateline'].'&endtime='.($blogs[$cur]['dateline'] + 86400).'" title=" '.$blogs[$cur]['num'].' "><b>'.$cur.'</b></a></td>';

}

}

$cal .= '';

}

return $cal;
