WP Redis - Predis Client

This is a package that enables the use of Predis as a Redis Client as opposed to PHPRedis for WP Redis. Predis has the distinct advantage of connecting to Redis via TLS, encrypting traffic in-transit. Requires WP Redis >= 0.7.0.

Getting Started

Requiring Files


When using Composer, functions.php file will automatically be loaded whenever you include Composer's autoloader in your project.

Manually Requiring

The only file needing require_onceing for WP Predis to work correctly is functions.php (which is automatically included via vendor/autoload.php, which is generated by Composer). Download this repo somewhere in your project, run composer install, and include vendor/autoload.php somewhere early (such as wp-config.php):

require_once '/path/to/wp-redis-predis-client/vendor/autoload.php';

Object Cache stub

Now that files have been included, it's recommended you use the included object-cache.php file instead of the one included with WP Redis. It will add the required filters for WP Predis to work and then include WP Redis' object-cache.php file. Once object-cache.php is in wp-content (or whatever content directory you are using), you're good to go!

Configuring Predis

WP Redis - Predis Client adheres to WP Redis' configuration details. Predis also takes an additional argument, ssl, for configuring TLS connections. See PHP's SSL Context options for more details.

global $redis_server;
$redis_server = array(
    'host' => '',
    'port' => 6379,
    'ssl'  => array(
        'local_cert' => '/path/to/certificate_and_key.pem',
        'verify_peer' => true,
