PHP Operation Redis

Redis is an open source API that is written in ANSI C, supports the web, can be persisted in memory, key-value databases, and provides multiple languages.

The data types supported by Redis are STIRNG (strings), list (lists), Hash (dictionary), set (set), Sorted set (ordered set);

The Redis version is the Redis 2.6.12 system in windows+apache2.4+php5.6

Connection:

1     //instantiation Redis2     $redis = new Redis (), 3     //Connection 4     $redis->connect (' 127.0.0.1 ', 6379); 5     //Detect connection successful 6     echo "Server is running:". $redis->ping (); 7     //Output result Server is running: +pong    

Strng (String):

Sets the value of a string    $redis->set (' Cat ', 111);    Gets the value of a string    echo $redis->get (' cat ');//111    //Repeat set    $redis->set (' Cat ', 222);    echo $redis->get (' cat '); 222

List (lists):

 1//List 2//store data to List 3 $redis->lpush (' list ', ' HTML '), 4 $redis->lpush (' list ', ' CSS '), 5 $re Dis->lpush (' list ', ' php '); 6 7//Get all the values in the list 8 $list = $redis->lrange (' list ', 0,-1); 9 Print_r ($list); Echo ' <br> '; 10 11//Add a $redis->rpush (' list ', ' MySQL ') from the right, $list = $redis->lrange (' list ', 0,-1); Print_r ($list); Echo ' <br> '; 15 16//Eject a $redis->lpop (' list ') from the left, $list = $redis->lrange (' list ', 0,-1 ); Print_r ($list); Echo ' <br> '; 20 21//Eject a $redis->rpop (' list ') from the right, $list = $redis->lran  GE (' list ', 0,-1); Print_r ($list); Echo ' <br> '; 25 26//Results//Array ([0] + + PHP [1] + CSS [2]  + HTML)//array ([0] = + php [1] = + CSS [2] + + HTML [3] = MySQL)//Array ([0] + CSS [1] + + HTML [2] = MySQL)/Array ([0] = + CSS [1] + HTML)
