Redis is a high-performance key-value database. The emergence of redis has largely compensated for the shortcomings of key/value storage such as memcached, and can play a very good supplementary role to relational databases in some situations. It provides Java, C/C++, C#, PHP, JavaScript, Perl, Object-C, Python, Ruby, Erlang and other clients, which is very convenient to use. "Black Horse Cloud Classroom NoSQL Redis Technology Video Tutorial" will help you understand Redis technology.

The teacher’s teaching style:

The teacher’s lectures are vivid, witty, witty, and touching. A vivid metaphor is like the finishing touch, opening the door to wisdom for students; a well-placed humor brings a knowing smile to students, like drinking a glass of mellow wine, giving people aftertaste and nostalgia; a philosopher's aphorisms, cultural references Proverbs are interspersed from time to time in the narration, giving people thinking and alertness.

The more difficult point in this video is to operate redis with PHP:

Redis is an open source software written in ANSI C language, supports the network, and can be memory-based or persistent. Log-type, Key-Value database, and provides APIs in multiple languages.

The data types supported by Redis are Stirng (string), List (list), Hash (dictionary), Set (set), Sorted Set (ordered set);

The redis version is Redis 2.6.12 system is under Windows+Apache2.4+php5.6

Connection:

//实例化redis
    $redis = new Redis();
    //连接
    $redis->connect('127.0.0.1', 6379);
    //检测是否连接成功
    echo "Server is running: " . $redis->ping();
    // 输出结果 Server is running: +PONG

Strng(String):

// 设置一个字符串的值
    $redis->set('cat', 111);

    //获取一个字符串的值
    echo $redis->get('cat'); // 111

    // 重复set
    $redis->set('cat', 222);
    echo $redis->get('cat'); // 222

List(List):

//列表
    //存储数据到列表中
    $redis->lpush('list', 'html');
    $redis->lpush('list', 'css');
    $redis->lpush('list', 'php');

    //获取列表中所有的值
    $list = $redis->lrange('list', 0, -1);
    print_r($list);echo &#39;<br>&#39;; 

    //从右侧加入一个
    $redis->rpush(&#39;list&#39;, &#39;mysql&#39;);
    $list = $redis->lrange(&#39;list&#39;, 0, -1);
    print_r($list);echo &#39;<br>&#39;;

    //从左侧弹出一个
    $redis->lpop(&#39;list&#39;);
    $list = $redis->lrange(&#39;list&#39;, 0, -1);
    print_r($list);echo &#39;<br>&#39;;

    //从右侧弹出一个
    $redis->rpop(&#39;list&#39;);
    $list = $redis->lrange(&#39;list&#39;, 0, -1);
    print_r($list);echo &#39;<br>&#39;;

    // 结果
    // 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 )
