Connect with PHP
This example connects to Redis®* service from PHP, making use of the
predis
library.
Variables
These are the placeholders you will need to replace in the code sample:
Variable | Description |
---|---|
REDIS_URI | URL for the Redis connection, from the service overview page |
Prerequisites
Install the predis
library:
composer require predis/predis
Code
Create a new file named index.php
, add the following content and
replace the placeholder with the Redis URI:
<?php
require 'vendor/autoload.php';
Predis\Autoloader::register();
$redis_uri = 'REDIS_URI';
$client = new Predis\Client($redis_uri);
$client->set('key', 'hello world');
$value = $client->get('key');
echo "The value of key is: {$value}";
This code creates a key named key
with the value hello world
and no
expiration time. Then, it gets the key back from Redis and prints its
value.
Run the code:
php index.php
If the script runs successfully, the outputs should be:
The value of key is: hello world
