question HTML5/CSS3/PHP Beautifiers

[Name Trader]

I always have a problem finding the right forum for development type of questions. This was the best I could find for this question. Mods feel free to move it somewhere more appropriate if necessary.

I'd like some recommendations for the best HTML/CSS/PHP Beautifiers

I'd like some recommendations for HTML5/CSS3 Validators besides W3C. I want them to strictly validate HTML5 and CSS3 code.
