trying to make characters safe for my RSS feed

[lkrubner]

Whenever users write a post in Microsoft Word and then post it to
their weblogs using my PHP software, their RSS feed ends up being
corrupted with garbage characters which violate the well-formedness of
their XML and therefore cause their newsreaders to die.

This function will probably make the character strings completely safe
for XML? I don't care about having garbage characters in the RSS feed,
I just want the RSS feed to show up, without causing anyone's newsfeed
reader to die.
function command($string=false) {
$howMany = strlen($string);

$newString = "";
for ($i=0; $i < $howMany; $i++) {
$char = $string[$i];
$asciiNum = ord($char);
if ($asciiNum > 32 && $asciiNum < 128) {
$newString .= $char;
} else {
$newString .= "'";
}
}

return $newString;
}

Okay, the function doesn't work:

All the white space got replaced, but the entity that is kill the feed
is still there.

What is wrong with this function?

function command($string=false) {
$howMany = strlen($string);

$newString = "";
for ($i=0; $i < $howMany; $i++) {
$char = $string[$i];
$asciiNum = ord($char);
if ($asciiNum > 32 && $asciiNum < 128) {
$newString .= $char;
} else {
$newString .= "'";
}
}

return $newString;
}

I don't know what's wrong with its operation, but you're reinventing the
wheel.

I apologize for my ignorance, but I don't see how that reinvents the
wheel. The function you point to would allow me to replace the
offending character if I knew what it was, but I don't know what it
is.That's why I'm walking through the string one character at a time,
checking its ASCII number. Yet even that isn't working. I can't figure
out why. But that's the question.
