Rounding with error message

[Porl123]

I've been making this roulette page in php for the last day or so and everything's fine except this one error message that isn't showing up.

I have the outcome to the wheel, betting on red/black, odd/even all put into the arrays $bet[] and $won[] and I've used array_sum to get them afterwards. I've tried to make sure they're using whole numbers by putting in

if(!round(array_sum($bet))) {

echo "Invalid bet";

}

 

I was hoping that would just work on its own, but you can still place bets containing decimal places if there's at least one box filled with a whole number. Anyone have any ideas? I'd be really grateful :] thanks

To check if a value is a round number with no decimal places, ctype_digit() should work (http://www.php.net/manual/en/function.ctype-digit.php).

 

Also you can/probably should cast the type to an integer value before doing anything with it just to be sure.

 

$var = (int)$var;

That's working but for some reason anything below 256 sets off the error message too :[

Why not just check to see if there is a period (.) in the variable?

 

$dec = 46.4;
if(strstr($dec,".")){
die("You have a decimal!");
}

 

That there will die with the error message.
