You want to use the Redis key-value store from your PHP program.
If you can install PECL extensions, install the redis extension and then use it as follows:
|
1 2 3 4 5 6 |
$redis = new Redis(); $redis->connect('127.0.0.1'); $redis->set('counter', 0); $redis->incrBy('counter', 7); $counter = $redis->get('counter'); print $counter; |
If you can’t, use the Predis library:
|
1 2 3 4 5 6 7 8 |
require 'Predis/Autoloader.php'; Predis\Autoloader::register(); $redis = new Predis\Client(array('host' => '127.0.0.1')); $redis->set('counter', 0); $redis->incrBy('counter', 7); $counter = $redis->get('counter'); print $counter; |
Although the redis extension and Predis library differ in how they are installed and how you connect to a server, they behave similarly in many respects.
Each gives you an object representing a connection to a Redis server (or a pool of Redis servers) and that object has methods corresponding to the different operations you can send to the server(s).
To install the redis extension, use the pecl command:
|
1 |
pecl install redis |
To install Predis, use pear:
|
1 2 |
pear channel-discover pear.nrk.io pear install nrk/Predis |
If you are using the Composer package manager, install Predis with a dependency string of “predis/predis”.
