/* Determine if the data transfer is digital
Use regular expressions to determine if the number entered is legal
Call: Checknum (parameter 1, parameter 2)
*/

Copy the Code code as follows:

function Checknum ($id, $say)
{
$inid = $id;
if (!ereg ("^ (-{0,1}|\+{0,1}) [0-9]+ (\.{ 0,1}[0-9]+) ($ ", $inid))
{
echo $say. ", Entrance:". "". $inid. "";
Exit
}
}
