Currently I have this: if($quant > $amount) {echo "You don't have that many!"; } $quant is the user inputted amount and $amount is the amount that they actually have. Is there any way of checking if the result is negative rather than doing what I have above?

I'm not sure which "result" you are refering to, but this echo's if:

    $quant is greater than $amount
    $amount is less than 0
    $quant is less than 0

if ($quant > $amount or $amount < 0 or $quant < 0) {

    echo "You don't have that many!";
