What are the best practices for handling multiple instances of a PHP script on different servers without sharing data?

When handling multiple instances of a PHP script on different servers without sharing data, it is important to use a distributed cache system to store and retrieve data. This ensures that each instance of the script has its own copy of the data and does not rely on shared resources. One popular solution is to use Redis as a distributed cache system to store and retrieve data efficiently. 

// Example PHP code using Redis for handling multiple instances without sharing data

// Connect to Redis server
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

// Set data in Redis
$redis->set('key', 'value');

// Get data from Redis
$data = $redis->get('key');

// Use the data as needed
echo $data;
