Breaking W3C Validity

Hi, could you improve this class so that it doesn't break W3C standards.

I have only noticed "&" doesn't get converted to "&"

I'm gonna try converting the imported XML - so that it transforms "&" to "&"

Thanks
Paul

I put together this new function:

I called it in function readPosts()
with: $description = $this->convertAmpersand($description);

function convertAmpersand($description) {
$arr = explode(' ', $description);
echo count($arr);
foreach ($arr as $word) {
$wArr = str_split($word);
foreach ($wArr as $char) {
if ($char === "&") {
echo "&";
}
else {
echo $char;
}
}
echo ' ';
}
}
Seems to work well - maybe it might be done better by using a htmlentities / something to convert each char to HTML.
