Do you really just want to strip all non-numeric chars, even if it may
completely change the number? Nothing easier than that with a regex:

$value = preg_replace('/[^[:digit:]]/', '', $value);

should strip all chars that are no digits.

OK - this works -

$value = str_replace(",","",str_replace("$","",$value));

I suppose I could do -

$search = array("$",",");
$replace = array("","");
$value = str_replace($search,$replace,$value);

Aha - I could just replace those characters with null using strtr($value,
'$,',','), no?
