Pretty-print HTML via PHP without validation?

I'd like to automatically pretty-print (i开发者_如何学Pythonndentation, mostly) the HTML output that my PHP scripts generate. I've been messing with Tidy, but have found that in its efforts to validate and clean my code, Tidy is changing way too much. I know Tidy's intentions are good but I'm really just looking for an HTML beautifier. Is there a simpler library out there that can run in PHP and just do the pretty-printing? Or, is there a way to configure Tidy to skip all the validation stuff and just beautify?

The behaviour that you've observed when using Tidy is a result of the underlying use of DOM API. Instead of manipulating the provided source code, DOM API will reconstruct the whole source, thus making fixes along the way.

I've written Dindent, which is a library that uses Regex. It does not do anything beyond adding the indentation and removing whitespaces. However, I advise against using this implementation beyond development purposes.

I've never used Tidy but it seems pretty customizable.

Here's the quick reference of configuration options: http://tidy.sourceforge.net/docs/quickref.html

But really, with tools like Firebug, I've never seen the need to Tidy HTML output.

Since you do not want to have it validate for whatever reason, I will not suggest htmlpurifier ; ). Why not just use an IDE to get everything indented nicely, like Alt-Shift-F in Netbeans.

Facing the same problem i currently use a combination of two commands:

 cat template-home.php | js-beautify --type html | prettier --parser php

js-beautify formats the html bits and prettier formats the php code
