PHP 8.1 兼容性修改：使用 preg_replace_callback 重写输出内容

function rewrite_output($content) { $search = array( '/href="(./)?mod=(index|webdir|weblink|article|category|update|vipmulu|webthumb|archives|top|feedback|link)?"/', '/href="(./)?mod=webdir([&|&]cid=(\d+))?([&|&]page=(\d+))?"/', '/href="(./)?mod=article([&|&]cid=(\d+))?([&|&]page=(\d+))?"/', '/href="(./)?mod=update([&|&]days=(\d+))?([&|&]page=(\d+))?"/', '/href="(./)?mod=vipmulu([&|&]days=(\d+))?([&|&]page=(\d+))?"/', '/href="(./)?mod=archives([&|&]date=(\d+))?([&|&]page=(\d+))?"/', '/href="(./)?mod=search([&|&]type=(.+?))?([&|&]query=(.+?))?([&|&]page=(\d+))?"/', '/href="(./)?mod=siteinfo[&|&]wid=(\d+)"/', '/href="(./)?mod=diypage[&|&]pid=(\d+)"/', '/href="(./)?mod=rssfeed([&|&]type=(webdir|article))?([&|&]cid=(\d+))?"/', '/href="(./)?mod=sitemap([&|&]type=(webdir|article))?([&|&]cid=(\d+))?"/', );
