make sure a number does not have a .

[jasondavis]

I have form that post a number to my script

$number

I need to make sure $number is always a number between 1-10 digits long and does not contain a period so 123.45 would show up as 123

If you want to validate it and either accept or reject it:

if(ctype_digit($number) and $number strlen($number) <= 10)
{
   // valid
}
else
{
   // invalid
}

If you just want to convert, you could use the [man]round[/man] function.

this line gave me errors
unexpected T_STRING

if(ctype_digit($amount) and $amount strlen($amount) <= 10){

Im trying this with the use of ! but it seems to always return
ERROR: Whole dollar amounts only please

if(!ctype_digit($amount)){
 $msg = "ERROR: Whole dollar amounts only please";
$_SESSION['sess_msg'] = $msg;
header("location: $SITE_PATH?p=account.money&r=$receiver");
exit;
}

Sorry, I think I changed my mind in mid-stream of typing that line.

if(ctype_digit($amount) and strlen($amount) <= 10)
