我使用 php tidy 处理数据库中的 html 输入，
$fragment = tidy_repair_string($dom->saveHTML(), array('output-xhtml'=>1,'show-body-only'=>1));
我在我的服务器上打开了这个 php_tidy 但我的实时服务器不支持整洁，
致命错误：在第 587 行的 /customers/0/5/a/mysite.com/httpd.www/models/functions.php 中调用未定义的函数 tidy_repair_string()
我有什么办法可以解决这个问题吗？
我发现htmLawed非常快。我在寻找 HTMLPurifier 的替代品时发现了它，它非常慢。
或者简单地通过 DOMDocument 对象：
$dirty = "<xml>some content</xml>"
$x = new DOMDocument;
$x->loadHTML($dirty);
$clean = $x->saveXML();
如果您在 RedHat / CentOS / Fedora linux 机器上并且对您的服务器具有 root 访问权限，您可以运行...
yum install php-tidy
作为根。然后重新启动apache，这应该可以让您继续前进。
可能有关于缺少需要添加的依赖项的错误，但通常上面的命令就是你所需要的。
其他发行版的命令会略有不同，但应该可以使用类似的命令。
在 Windows 上，您需要手动安装它。说明可以在这里找到... http://devzone.zend.com/article/761#Heading3
HTML Purifier可以像 HTML Tidy 一样重写 HTML 以符合标准。如果您需要过滤该输入以防止 XSS 等，它也会这样做。
都是PHP，所以你应该可以在任何服务器上使用它。
PHP 超级整洁？
我厌倦了 PHP Tidy 的糟糕工作，所以我开始写这个。它也应该整理任何 javascript。它没有经过全面测试，因此您可能会发现一些需要考虑的意外情况。很高兴看到其他一些有才华的开发人员对此进行阐述。PS我知道这是一个旧线程，但我想在某个地方分享这个......
这是一个开始。享受。
