predisHow can I use the PHP Redis HGET command?

The HGET command in PHP Redis is used to retrieve the value of a field in a hash stored at a given key.

<?php

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

$user = $redis->hGet('user', 'name');

echo $user;

// Output: John
?>

In the example above, we connect to a Redis server on 127.0.0.1 port 6379, and then use the hGet command to retrieve the value of the name field in the user hash. The output of the code above is John.

The following parts are used in the example code:

• Redis - The Redis class in the PHP Redis extension.
• connect - A method that connects to a Redis server.
• hGet - The hGet command, which retrieves the value of a field in a hash stored at a given key.

For more information, see the PHP Redis documentation.
