[O] font-lock error on html export with src blocks

[Matt Price]

Hi everyone,

I'm having trouble exporting an org file  to html, or any html-derived
backends (deck, wordpress, etc).  I've attached a version of the
offending file but I've also narrowed the error down to one php source
block:

#+BEGIN_SRC php
/* Register SoundCloud shortcode
   -------------------------------------------------------------------------- */

add_shortcode("soundcloud", "soundcloud_shortcode");


/**
 * SoundCloud shortcode handler
 * @param  {string|array}  $atts     The attributes passed to the
shortcode like [soundcloud attr1="value" /].
 *                                   Is an empty string when no
arguments are given.
 * @param  {string}        $content  The content between non-self
closing [soundcloud]â EURO |[/soundcloud] tags.
 * @return {string}                  Widget embed code HTML
 */
function soundcloud_shortcode($atts, $content = null) {

#+END_SRC

The error seems to be related to font locks, and I guess must have
something to do with php-mode somehow:

Does anyone else have any suggestions?  thanks!
