Test if a number is positive and contains only 0-9:
function is_number($number)
{
$text = (string)$number;
$textlen = strlen($text);
if ($textlen==0) return 0;
for ($i=0;$i < $textlen;$i++)
{ $ch = ord($text{$i});
if (($ch<48) || ($ch>57)) return 0;
}
return 1;
}
returns
0 : number contain character outside 0-9
1 : valid number.
