"$2,090.99 "

"209099"

You can use a regular expression to replace everything that is not a digit:

$output = preg_replace('/\D/', '', $str);

\D is equivalent to [^\d] that is equivalent to [^0-9].

You might be better off using PHP 5.3's MessageFormatter, Locale and Intl classes if you'll be handling different locales and currency formats. The msgfmt_parse() method might just be what you need.
