我使用php tidy来处理我的数据库中的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但是我的直播服务器不支持整洁，
致命错误：调用未定义的函数tidy_repair_string（） 第587行/customers/0/5/a/mysite.com/httpd.www/models/functions.php
我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，这非常慢。
答案 1 :(得分：6)
或者只是传递DOMDocument对象：
$dirty = "<xml>some content</xml>"
$x = new DOMDocument;
$x->loadHTML($dirty);
$clean = $x->saveXML();

如果您使用的是RedHat / CentOS / Fedora Linux机箱并拥有对服务器的root访问权限，则可以运行...
yum install php-tidy
以root身份。然后重启apache，这应该让你去。
可能存在关于缺少需要添加的依赖项的错误，但通常上述命令将是您所需要的。
其他发行版的命令略有不同，但应该有类似的内容。
在Windows上，您需要手动安装它。可以在此处找到说明... http://devzone.zend.com/article/761#Heading3
答案 3 :(得分：4)
HTML Purifier可以将HTML重写为符合标准的like HTML Tidy。如果您需要过滤该输入以进行XSS预防等，它也会这样做。
这都是PHP，所以你应该可以在任何服务器上使用它。

PHP SuperTidy？
我对PHP Tidy的工作效率感到厌倦，所以我开始写这个。它也应该整理所有JavaScript。它没有经过充分测试，因此您可能会发现一些需要考虑的意外情况。看到其中一些其他才华横溢的开发人员对此进行说明，将很有趣。附言我知道这是一个旧线程，但是我想在某个地方共享它...
这是一个开始。享受。
