I am looking for advice on the correct doctype for my website <snip> this is a php website but this is at the top of all my pages
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
</html xmlns="http://www.w3.org/1999/xhtml">

Is this the correct doctype to be using for a php website?

PHP (or how you generate your pages) has nothing to do with it.

If your site really is XHTML then what you have is probably OK (although you have a slash in your opening HTML tag - this is wrong).

However, for any new content you should probably be serving HTML with an HTML5 doctype. Which is simply:


<!DOCTYPE html>

Have you tried feeding a few random pages into the HTML validator? If the doctype doesn't match the page content, it will yap loudly. A few-- not many-- features of HTML vs. XHTML are mutually exclusive.

A lot of editors (CMS, WYSIWYG) seem to like producing XHTML Strict. There is presumably a boring historical reason for this.
