predisHow can I use a Redis hash in a PHP application?

Hash data type in Redis is used to store key-value pairs in a single data structure. It can be used in a PHP application to store data in an efficient way.

Example code

<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);

$redis->hSet('user:1', 'name', 'John');
$redis->hSet('user:1', 'age', '25');

echo $redis->hGet('user:1', 'name'); // John
echo $redis->hGet('user:1', 'age');  // 25

Parts of the code:

1. $redis = new Redis(); - Create a new Redis connection.
2. $redis->connect('127.0.0.1', 6379); - Connect to Redis server.
3. $redis->hSet('user:1', 'name', 'John'); - Set a key-value pair in the hash.
4. $redis->hSet('user:1', 'age', '25'); - Set a key-value pair in the hash.
5. echo $redis->hGet('user:1', 'name'); - Get a value from the hash using the key.
6. echo $redis->hGet('user:1', 'age'); - Get a value from the hash using the key.
