Thanks all for pointing me in the right direction.

One of the main bits was that there's a way to check whether certain "atoms"
are numeric which I think was [:isnum:], looking at the information here
http://www.php.net/manual/function.ereg.php it appears that using [0-9] also
works. So I would suggest something along the lines of

if (ereg("^[,.0-9]+$", $amount) {
 do something;
} else {
 complain loudly;
