PHP Using Redis with PHP
Connecting to a Redis instance
Assuming a default server running on localhost with the default port, the command to connect to that Redis server would be:
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);Installing PHP Redis on Ubuntu
To install PHP on Ubuntu, first install the Redis server:
sudo apt install redis-server
then install the PHP module:
sudo apt install php-redis
And restart the Apache server:
sudo service apache2 restartExecuting Redis commands in PHP
The Redis PHP module gives access to the same commands as the Redis CLI client so it is quite straightforward to use.
The syntax is as follow:
// Creates two new keys:
$redis->set('mykey-1', 123);
$redis->set('mykey-2', 'abcd');
// Gets one key (prints '123')
var_dump($redis->get('mykey-1'));
// Gets all keys starting with 'my-key-'
// (prints '123', 'abcd')
var_dump($redis->keys('mykey-*'));
