$number = $_POST['inputBox'];
Code you want to run if number was inputted
Code you want to run if number was NOT inputted
Is that what you're after?

So the is_numeric function will tell me if the value of a string variable is actually a number?
Finds whether the given variable is numeric. Numeric strings consist of optional sign, any number of digits, optional decimal part and optional exponential part. Thus +0123.45e6 is a valid numeric value. Hexadecimal notation (0xFF) is allowed too but only without sign, decimal and exponential part.
might also want to take a look at http://php.net/filter
