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 maykonn/codeigniter-predis or if not:, (*1)
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, (*2)
Using
1) Install the Redis server, read the Redis documentation., (*3)
2) Import the src/Redis.php file:, (*4)
require_once APPPATH . 'libraries/codeigniter-predis/src/Redis.php';
3) Load the library to your CodeIgniter instance:, (*5)
$this->redis = new \CI_Predis\Redis(['serverName' => 'default']);
4) Test:, (*6)
echo $this->redis->ping();
5) See the example here, (*7)
You can perform redis commands in three different ways:, (*8)
Will call the command on the current setted server, to change server use $redis->connect() method:, (*9)
$redis->some_redis_command();
Alias to the code above:, (*10)
$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), (*11)
$redis->getServersCollection()->getServer('some_server')->some_redis_command();
