An even better version of the function in that it copes with 0's, as well as , and . for
thousends seperators and decimal points
function is_num($var) {
for ($i=0;$i<strlen($var);$i++) {
$ascii_code=intval(ord($var{$i}));
if (($ascii_code >=48 && $ascii_code <=57) || $ascii_code ==46 || $ascii_code ==44)
{
continue;
} else {
return false;
}
}
return true;
}
