Hi

What's the maximum value for an integer in PHP (WIN XP).
Is there a constant or function that returns this value?

id imagine that a integer can be as long as you want it to be. why would there be a restriction?

At some point a number will go from int to double... When does this happen?

Code: Select all

define('MAXINT', 2147483647);
define('MININT', -2147483648);
An int spans from -2^31 ro 2^31-1. In php an int is made up from 32 bits where 1 bit is a sign bit.
