Before you start using Redis in your PHP programs, you need to make sure that you have Redis PHP driver and PHP set up on the machine. You can check PHP tutorial for PHP installation on your machine.
Installation
Now, let us check how to set up Redis PHP driver.
You need to download the phpredis from github repository https://github.com/nicolasff/phpredis. Once you’ve downloaded it, extract the files to phpredis directory. On Ubuntu, install the following extension.
cd phpredis sudo phpize sudo ./configure sudo make sudo make install
Now, copy and paste the content of “modules” folder to the PHP extension directory and add the following lines in php.ini.
extension = redis.so
Now, your Redis PHP installation is complete
Connect to Redis Server
<?php //Connecting to Redis server on localhost $redis = new Redis(); $redis->connect(''127.0.0.1'', 6379); echo "Connection to server sucessfully"; //check whether server is running or not echo "Server is running: ".$redis->ping(); ?>
When the program is executed, it will produce the following result.
Connection to server sucessfully Server is running: PONG
Redis PHP String Example
<?php //Connecting to Redis server on localhost $redis = new Redis(); $redis->connect(''127.0.0.1'', 6379); echo "Connection to server sucessfully"; //set the data in redis string $redis->set("tutorial-name", "Redis tutorial"); // Get the stored data and print it echo "Stored string in redis:: " .$redis→get("tutorial-name"); ?>
When the above program is executed, it will produce the following result.
Connection to server sucessfully Stored string in redis:: Redis tutorial
Redis php List Example
<?php //Connecting to Redis server on localhost $redis = new Redis(); $redis->connect(''127.0.0.1'', 6379); echo "Connection to server sucessfully"; //store data in redis list $redis->lpush("tutorial-list", "Redis"); $redis->lpush("tutorial-list", "Mongodb"); $redis->lpush("tutorial-list", "Mysql"); // Get the stored data and print it $arList = $redis->lrange("tutorial-list", 0 ,5); echo "Stored string in redis:: "; print_r($arList); ?>
When the above program is executed, it will produce the following result.
Connection to server sucessfully Stored string in redis:: Redis Mongodb Mysql
