str_replace all punctuation?

[conker87]

I'm looking for a way of removing all punctuation (and everything not letters and numbers), however I'd also like to replace the apostrophe (') and a space with a dash (-). Anyone got any ideas?

$string = "This.has,a ;lot! of's pun?tu030ation";

echo foo($string);

function foo($string)
{
$string = preg_replace('/[\'\s]+/', '-', $string);

$string = preg_replace('/[^\-a-zA-Z0-9\s]+/', '', $string);

return $string;
}
