Are there ways to increase the storage capacity or declare a large data type in PHP?

In PHP, the storage capacity of a variable is determined by its data type. If you need to store larger values than what the default data types can handle, you can use the `gmp` extension to work with arbitrary precision numbers. This extension allows you to perform mathematical operations on numbers with virtually unlimited precision. 

// Enable the GMP extension
extension_loaded('gmp') or die('GMP extension not available');

// Declare a large number using the gmp_init function
$largeNumber = gmp_init('123456789012345678901234567890');

// Perform operations on the large number
$sum = gmp_add($largeNumber, gmp_init('987654321098765432109876543210'));

// Convert the result back to a regular integer for output
echo gmp_strval($sum);
