dedecms统计当前文章的字数

在/include/extend.func.php文件最底部添加：

// 统计文章字数
function strlen_utf8($str) {
    $i = 0;
    $count = 0;
    $str = Html2text($str);
    $len = strlen($str);
    while ($i < $len) {
        $chr = ord($str[$i]);
        $count++;
        $i++;
        if ($i >= $len) {
            break;
        }
        if ($chr & 0x80) {
            $chr <<= 1;
            while ($chr & 0x80) {
                $i++;
                $chr <<= 1;
            }
        }
    }
    return $count;
}

前台调用标签为：

{dede:field.body function='strlen_utf8(@me)'/}

例如：方圆建筑圆模板网详细页面的代码为：

<div class="content" id="content">
                <h2>{dede:field.title/}</h2>
                <div class="art_info"><span>发布时间：{dede:field.pubdate function="MyDate('Y-m-d H:i:s',@me)"/}</span> <span>编辑：{dede:field.writer/}</span> <span>来源：{dede:field.source/}</span> <span>阅读：{dede:field name='suiji' runphp='yes'}@me = (rand(50,999));{/dede:field}次</span><div class="keyword">关键字：{dede:field.keywords/}</div></div>
                <div class="article" id="content">
