PEAR standards are fairly well-accepted:

PEAR actually recommends this latter instead of the former; the only
case they make for opening braces on the following line is with class
and function/method definitions. (I personally don't understand why
these are treated differently, but I'm sure there's some discussion in
the mailing lists that treats it.)

I personally try not to put HTML into my code, and use templates:
* Placing HTML into PHP means I'm having to try and decipher two
languages (or more, if I use CSS or Javascript) in the same file;
making the mental switch in the same file is typically more difficult
than having HTML/CSS/JS in different files.
* If I need to worry about HTTP headers deep into the program logic (for
instance, to perform a redirect or set a cookie), I don't want to
worry about whether or not any HTML has been sent to the screen.
* If I need to fix a typo in the HTML, I don't want to browse through a
bunch of PHP to find it.
When I *do* place HTML in my PHP (it *does* happen occasionally), I
typically use heredocs so I don't have to worry about quotes and such:
$html =<<<EOH
<h1>Test</h1>
<p>This is a test of the emergency HTML situation</p>
<p>It received $error_signal</p>
EOH;
However, all the above is my personal coding preference; I've heard very
good arguments for other styles and for not using templates.
