Connect with PHP

Learn how to connect to an Aiven for Caching service using PHP and the predis library, complete with code examples and setup instructions.

Variables​

Replace the following placeholders in the code sample with actual values from your service overview page:

VariableDescription
SERVICE_URIURI for the Aiven for Caching service connection

Prerequisites​

To install the predis library, run the following command:

composer require predis/predis

Code​

Create a file named index.php and insert the code below, substituting the placeholder with your Aiven for Caching 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 without an expiration. It then retrieves this key from the caching service and outputs its value.

Execute the script with:

php index.php

Successful execution results in the following output:

The value of key is: hello world
