Re: problem with intval and !=

Curt: My fault! You are right, but thats not what I want. $value comes from a form filled by a user. I want $value to be an integer. Not a float. So if the user types "12.3" the system has to send an error msg. Therefore the procedure. By-the-way, Im using PHP 4.3.3 (on windows XP profesional. Don't say a thing!!! I rather work on my mac!) =) Cesar Curt Zirzow wrote:

Can somebody explain me why is this happening? $value = "12.3"; $number = intval($value); echo "Number: $number, Value: $value<br>"; // echoes: Number: 12, Value: 12.3

I'm guessing you wondering why the .3 is removed. Thats because 12.3 isn't an integer but a float. $number = floatval($value);

if ($number != $value) { echo "Bad"; } else { echo "Good"; // echoes Good!!!!!! } The previous should be echoing "Bad". (I think!)

correct. If you use the floatval() it will echo "Good". Curt
