[PHP] Attempt at putting greedy htmlspecialchars on a diet

[Gerard Samuel]

Got a problem with htmlspecialchars being too greedy, where
for example, it converts
&foo;
to
&foo;
Yes it displays correctly in the browser for some content, but not all.  
(an example is posted below)
So I came up with this example code, but not sure if there is an 
easier/better way to get the correct end result.
If there is a better way, feel free to let me know.
Thanks

Note: I dont read/speak chinese, so if its offensive please forgive me.

------
<?php
$foo = '&#20013;&#25991; & http://www.foo.com/index.php?foo=1&bar=2';

// Original string with chinese output but not XHTML friendly
echo "<p>$foo</p>\n\n";
$foo = htmlspecialchars($foo);

// After htmlspecialchars, XHTML is friendly but has broken chinese output
echo "<p>$foo</p>\n\n";
$foo = preg_replace('/&amp;(#?[a-z0-9]+;)/', '&' . '$1', $foo);

// Both XHTML friendly and correct chinese output
echo "<p>$foo</p>";
?>
