第一步，找到e文件夹下的class文件夹里userfun.php这个文件，复制进去。
function ddtext($str){
global $empire, $dbtbpre, $public_r, $class_r;
$sql = $empire->query(\"select * from {$dbtbpre}ecms_k\"); /
while($r=$empire->fetch($sql)) {
$titleurl=sys_ReturnBqTitleLink($r);
$titleurl = str_replace(\'index.html\', \'\', $titleurl);
$r[title] = preg_replace(\'/软件大全/i\', \'\', $r[title]);
$str = preg_replace(\'/\'.$r[title].\'(?!([^<]*>)|([^<]*<\\ a=\"\">))/i\', \'<a href=\'.$titleurl.\' target=_blank class=infotextkey>\'.$r[title].\'</a>\', $str, 1);
}
$str = preg_replace(\'/\\\\\\/\', \'\', $str);
$str = preg_replace(\'/(<[img|IMG].*?src=[\"|\\\'|])(.*?)/\', \'$1\'.$public_r[add_www_img].\'$2\', $str);
return $str;
}
第二步，前端调用标签
<?=ddtext($navinfor[newstext])?>
