页面加载耗时代码
function timer_start() {
global $timestart;
$mtime = explode( ' ', microtime() );
$timestart = $mtime[1] + $mtime[0];
return true;
}
timer_start();
function timer_stop( $display = 0, $precision = 3 ) {
global $timestart, $timeend;
$mtime = explode( ' ', microtime() );
$timeend = $mtime[1] + $mtime[0];
$timetotal = $timeend - $timestart;
$r = number_format( $timetotal, $precision );
if ( $display )
echo $r;
return $r;
}然后，模板部分加入<?php timer_stop() ?>【转自http://t.160.me/65.html】
文章中文字数统计
function art_count ($cid){
$db=Typecho_Db::get ();
$rs=$db->fetchRow ($db->select ('table.contents.text')->from ('table.contents')->where ('table.contents.cid=?',$cid)->order ('table.contents.cid',Typecho_Db::SORT_ASC)->limit (1));
$text = preg_replace("/[^\x{4e00}-\x{9fa5}]/u", "", $rs['text']);
echo mb_strlen($text,'UTF-8');

替换文章内容
function themeInit($archive)
{
if ($archive->is('single'))
{
$archive->content = image_class_replace($archive->content);
}
}
function image_class_replace($content)
{
$content = preg_replace('#<a(.*?) href="([^"]*/)?(([^"/]*)\.[^"]*)"(.*?)>#',
'<a$1 href="$2$3"$5 target="_blank">', $content);
return $content;
}上述代码就是将不含blank属性的超链接，替换为加上了blank属性的超链接
自定义上下篇链接
/**
* 显示下一篇
*
* @access public
* @param string $default 如果没有下一篇,显示的默认文字
* @return void
*/
function theNext($widget, $default = NULL)
{
$db = Typecho_Db::get();
$sql = $db->select()->from('table.contents')
->where('table.contents.created > ?', $widget->created)
->where('table.contents.status = ?', 'publish')
->where('table.contents.type = ?', $widget->type)
->where('table.contents.password IS NULL')
->order('table.contents.created', Typecho_Db::SORT_ASC)
->limit(1);
$content = $db->fetchRow($sql);
if ($content) {
$content = $widget->filter($content);
$link = '<a href="' . $content['permalink'] . '" title="' . $content['title'] . '">下一篇</a>';
echo $link;
} else {
echo $default;
}
}
/**
* 显示上一篇
*
* @access public
* @param string $default 如果没有下一篇,显示的默认文字
* @return void
*/
function thePrev($widget, $default = NULL)
{
$db = Typecho_Db::get();
$sql = $db->select()->from('table.contents')
->where('table.contents.created < ?', $widget->created)
->where('table.contents.status = ?', 'publish')
->where('table.contents.type = ?', $widget->type)
->where('table.contents.password IS NULL')
->order('table.contents.created', Typecho_Db::SORT_DESC)
->limit(1);
$content = $db->fetchRow($sql);
if ($content) {
$content = $widget->filter($content);
$link = '<a href="' . $content['permalink'] . '" title="' . $content['title'] . '">上一篇</a>';
echo $link;
} else {
echo $default;
}
}调用代码<?php thePrev($this); ?>和<?php theNext($this); ?>【转自http://t.160.me/33.html】
自定义分类、标签、搜索、首页等文章分页数量
function themeInit($archive) {
if ($archive->is('index')) {
$archive->parameter->pageSize = 10; // 自定义条数
}
}
上边的是自定义首页文章数量，下面的是自定义default文章数量
function themeInit($archive) {
if ($archive->is('category', 'default')) {
$archive->parameter->pageSize = 10; // 自定义条数
}

判断最新帖子显示图标
例如24小时内发布的贴，需要一个标志来完成。这里是用判断输入特殊字符，再用CSS判断完成的。
/**
* 判断时间区间
*
* 使用方法 if(timeZone($this->date->timeStamp)) echo 'ok';
*/
function timeZone($from){
$now = new Typecho_Date(Typecho_Date::gmtTime());
return $now->timeStamp - $from < 24*60*60 ? true : false;
}在index.php中调用<?php if(timeZone($this->date->timeStamp)) echo ' new'; ?>【转自http://t.160.me/44.html】
N天内评论最多的文章
代码作用是N天内评论最多的N篇文章，这个N你可以自己定义，自己修改。
<?php
function rmcp($days = 30,$num = 5){
$defaults = array(
'before' => '<ul>',
'after' => '</ul>',
'xformat' => '<li><a href="{permalink}">{title}</a><span class="subcolor">已有评论数：{commentsNum}</span></li>'
);
$time = time() - (24 * 60 * 60 * $days);
$db = Typecho_Db::get();
$sql = $db->select()->from('table.contents')
->where('created >= ?', $time)
->where('type = ?', 'post')
->limit($num)
->order('commentsNum',Typecho_Db::SORT_DESC);
$result = $db->fetchAll($sql);
echo $defaults['before'];
foreach($result as $val){
$val = Typecho_Widget::widget('Widget_Abstract_Contents')->filter($val);
echo str_replace(array('{permalink}', '{title}', '{commentsNum}'), array($val['permalink'], $val['title'], $val['commentsNum']), $defaults['xformat']);
}
echo $defaults['after'];
}
?>模板调用<?php rmcp(60,5);?>这个调用的意思是2个月内评论最多的前5篇文章。【转自http://t.160.me/85.html】
百度是否收录

在文章编辑页面设置个自定义字段
