When you run it, you should hopefully see the message “Successfully connected to Redis”. To test everything out, create the file test.php with the following content to test if you can successfully connect to the running Redis server with Predis: 'tcp', Otherwise you’ll need to download the ZIP archive and unpack it. If you have Git installed on your machine like I do, all you need to do is clone the Predis repository. For this article I’ll be using the Predis library, but you may also want to look into phpredis which gets compiled and installed as a PHP module.

There are Redis client libraries available for many languages and are listed on the Redis website, often times with several available for each language! For PHP, there are five. * The server is now ready to accept connections on port 6379 Once Redis is installed, you can run the server: /usr/local/bin/redis-server From my own experience, if you are running Ubuntu then you will get an error if you do not have TCL installed (simply run sudo apt-get install tcl). Redis is easy to install, and brief installation instructions are published on the product’s download page. In this article we’ll take a look at some of the basic but powerful commands that Redis has to offer using the Predis library. Redis has more features than Memcache, such as in-memory and disk persistence, atomic commands and transactions, and not logging every change to disk but rather server-side data structures instead. There is a lot of argument whether Redis or Memcache is better, though as the benchmarks show they perform pretty much on par with each other for basic operations. Documentation and more information on Redis and all of its commands can be found on the project’s website, redis.io. Redis also has a publish/subscribe system, which is great for creating an online chat or a live booking system. You can use Redis as a session handler, which is especially useful if you are using a multi-server architecture behind a load balancer. It was started in 2009 by Salvatore Sanfilippo and because of its popularity quickly grew, being chosen by big companies like VMware (who later hired Sanfilippo to work on the project full time), GitHub, Craigslist, Disqus, Digg, Blizzard, Instagram, and more (see redis.io/topics/whos-using-redis). Redis is an open source data structure server with an in-memory dataset that does much more than simple key/value storage thanks to its built-in data types.
