首先将以下函数加到themes/Joe/core/function文件中。
/**
* 全站字数
*/
function allOfCharacters() {
$chars = 0;
$db = Typecho_Db::get();
$select = $db ->select('text')->from('table.contents');
$rows = $db->fetchAll($select);
foreach ($rows as $row) { $chars += mb_strlen(trim($row['text']), 'UTF-8'); }
$unit = '';
if($chars >= 10000) { $chars /= 10000; $unit = '万'; }
else if($chars >= 1000) { $chars /= 1000; $unit = '千'; }
$out = sprintf('%.2lf %s',$chars, $unit);
return $out;
}
/**
* 在线人数
*/
function online_users() {
$filename='online.txt'; //数据文件
$cookiename='Nanlon_OnLineCount'; //Cookie名称
$onlinetime=30; //在线有效时间
$online=file($filename);
$nowtime=$_SERVER['REQUEST_TIME'];
$nowonline=array();
foreach($online as $line){
$row=explode('|',$line);
$sesstime=trim($row[1]);
if(($nowtime - $sesstime)<=$onlinetime){
$nowonline[$row[0]]=$sesstime;
}
}
if(isset($_COOKIE[$cookiename])){
$uid=$_COOKIE[$cookiename];
}else{
$vid=0;
do{
$vid++;
$uid='U'.$vid;
}while(array_key_exists($uid,$nowonline));
setcookie($cookiename,$uid);
}
$nowonline[$uid]=$nowtime;
$total_online=count($nowonline);
if($fp=@fopen($filename,'w')){
if(flock($fp,LOCK_EX)){
rewind($fp);
foreach($nowonline as $fuid=>$ftime){
$fline=$fuid.'|'.$ftime."\n";
@fputs($fp,$fline);
}
flock($fp,LOCK_UN);
fclose($fp);
}
}
echo "$total_online";
}
/**
* 访客总数
*/
function theAllViews(){
$db = Typecho_Db::get();
$row = $db->fetchAll('SELECT SUM(VIEWS) FROM `typecho_contents`');
echo number_format($row[0]['SUM(VIEWS)']);
}
/**
* 加载耗时
*/
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 = number_format( $timeend - $timestart, $precision );
$r = $timetotal < 1 ? $timetotal * 1000 . " ms" : $timetotal . " s";
if ( $display ) {
echo $r;
}
return $r;
}
之后在需要的位置添加函数调用即可,例如footer.php中添加
