How to Access and Use the BigInteger Class in PHP?

Accessing the Math_BigInteger Class in PHP

PHP provides a BigInteger class for handling large integer values beyond the limits of a regular integer data type. It is accessible through the Math_BigInteger class within the Math package. This package can be installed via Composer or manually downloaded from its official repository.

To use the BigInteger class, you can follow these steps:

1. Include the Math package:

   <code class="php">include('Math/BigInteger.php');</code>

2. Create BigInteger objects:

   <code class="php">$a = new Math_BigInteger(2);
   $b = new Math_BigInteger(3);</code>

3. Perform arithmetic operations:

   <code class="php">$c = $a->add($b);</code>

4. Get the result as a string:

   <code class="php">echo $c->toString(); // outputs 5</code>
