Re: [PHP] Forms and PHP variables
is_numeric() will work with variables just fine. So:
if (is_numeric($var)) {
print Yep, it's numeric;
} else {
print Nope, it sure isn't a number;
}
Make sure $var is defined. If it's coming from a
form then use $_POST['var'] or similar instead for
reasons described here:

Thanks for the info, but . is_numeric does not appear to accept

Use is_numeric()
http://www.php.net/is_numeric
See also the ctype functions which can
be read about here:
http://www.php.net/ctype
And yes, regular expressions are another
option but aren't needed here.
