predisHow do I use PHP to retrieve a value from Redis?
Using PHP to retrieve a value from Redis is quite simple. First, you will need to install the PHP Redis extension. Once installed, you can connect to a Redis server and retrieve a value.
Example code
<?php
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$value = $redis->get('my_key');
echo $value;
?>
The code above will connect to a Redis server on 127.0.0.1
port 6379
and retrieve the value of the key my_key
. The output of the code would be the value of my_key
.
The code consists of the following parts:
$redis = new Redis();
- This line creates a new Redis instance.$redis->connect('127.0.0.1', 6379);
- This line connects to a Redis server on127.0.0.1
port6379
.$value = $redis->get('my_key');
- This line retrieves the value of the keymy_key
.echo $value;
- This line prints out the value ofmy_key
.
