PHP Question

Is there a BigInteger class in PHP? If so, how do I access it or use it?

Answer Source

Hopefully helpfull links :

**EDIT: Math_BigInteger**

Example from http://phpseclib.sourceforge.net/documentation/math.html :

Implements an arbitrary precision integer arithmetic library. Uses gmp or bcmath, if available, and an internal implementation, otherwise.

```
<?php
include('Math/BigInteger.php');
$a = new Math_BigInteger(2);
$b = new Math_BigInteger(3);
$c = $a->add($b);
echo $c->toString(); // outputs 5
?>
```
