Redis for CodeIgniter

• Is possible to configure and use multiple redis servers in a CodeIgniter project
• Multiple servers configurations with one configuration file
• Multiple servers by project environment

Installation

If you are using composer, type: composer require gdakuzak/codeigniter-predis

If not:

1. Download the code as ZIP in Clone or download button
2. Extract the downloaded zip into your application/libraries/ directory
3. Rename the extracted directory to application/libraries/codeigniter-predis
4. In your terminal go to library directory and type: composer install
5. The installation will create a codeigniter-predis.php file into the application/config/ folder
6. See the example here

Using

1. Install the Redis server, read the Redis documentation.

2. Import the src/Redis.php file:

require_once APPPATH . 'libraries/codeigniter-predis/src/Redis.php';

1. Load the library to your CodeIgniter instance:

$this->redis = new \CI_Predis\Redis(['serverName' => 'default']);

1. Test:

echo $this->redis->ping();

1. See the example here

How to perform redis commands?

You can perform redis commands in three different ways:

Will call the command on the current setted server, to change server use $redis->connect() method:

$redis->some_redis_command();

Alias to the code above:

$redis->getServerConnected()->some_redis_command();

Call the command in a specific server that isn't the current connect server (but instantiated before using connect method)

$redis->getServersCollection()->getServer('some_server')->some_redis_command();
