PHP操作Redis的基本方法

1 redis 的连接 ：

 //实例化redis
$redis = new Redis();
//连接
 $redis->connect(&＃39;127.0.0.1&＃39;, 6379);
//检测是否连接成功
echo "Server is running: " . $redis->ping();
// 输出结果 Server is running: +PONG

2 redis 操作 Strng (字符串):

// 设置一个字符串的值
$redis->set(&＃39;cat&＃39;, 111);
//获取一个字符串的值
echo $redis->get(&＃39;cat&＃39;); // 111
// 重复set
$redis->set(&＃39;cat&＃39;, 222);
echo $redis->get(&＃39;cat&＃39;); // 222

3 redis 操作 List (列表):

  //存储数据到列表中
$redis->lpush(&＃39;list&＃39;, &＃39;html&＃39;);
$redis->lpush(&＃39;list&＃39;, &＃39;css&＃39;);
$redis->lpush(&＃39;list&＃39;, &＃39;php&＃39;);
//获取列表中所有的值
$list = $redis->lrange(&＃39;list&＃39;, 0, -1);
print_r($list);echo &＃39;
&＃39;; 
// Array ( [0] => php [1] => css [2] => html )
//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;
&＃39;;
// Array ( [0] => php [1] => css [2] => html [3] => mysql )
//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;
&＃39;;
// Array ( [0] => css [1] => html [2] => mysql )
//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;
&＃39;;
// Array ( [0] => css [1] => html )

4 redis 操作 Hash (字典):

connect(&＃39;127.0.0.1&＃39;, 6379);
//字典
//给hash表中某个key设置value
//如果没有则设置成功,返回1,如果存在会替换原有的值,返回0,失败返回0
echo $redis->hset(&＃39;hash&＃39;, &＃39;cat&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;   // 1
echo $redis->hset(&＃39;hash&＃39;, &＃39;cat&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;   // 0
echo $redis->hset(&＃39;hash&＃39;, &＃39;cat&＃39;, &＃39;cat1&＃39;);echo &＃39;
&＃39;;   // 0
echo $redis->hset(&＃39;hash&＃39;, &＃39;dog&＃39;, &＃39;dog&＃39;);echo &＃39;
&＃39;;   // 1
echo $redis->hset(&＃39;hash&＃39;, &＃39;bird&＃39;, &＃39;bird&＃39;);echo &＃39;
&＃39;;   // 1
echo $redis->hset(&＃39;hash&＃39;, &＃39;monkey&＃39;, &＃39;monkey&＃39;);echo &＃39;
&＃39;;   // 1
//获取hash中某个key的值
echo $redis->hget(&＃39;hash&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;  // cat1
//获取hash中所有的keys
$arr = $redis->hkeys(&＃39;hash&＃39;);
print_r($arr);echo &＃39;
&＃39;;
// Array ( [0] => cat [1] => dog [2] => bird [3] => monkey )
//获取hash中所有的值 顺序是随机的
$arr = $redis->hvals(&＃39;hash&＃39;);
print_r($arr);echo &＃39;
&＃39;;
 // Array ( [0] => cat1 [1] => dog [2] => bird [3] => monkey )
//获取一个hash中所有的key和value 顺序是随机的
$arr = $redis->hgetall(&＃39;hash&＃39;);
print_r($arr);echo &＃39;
&＃39;;
 // Array ( [cat] => cat1 [dog] => dog [bird] => bird [monkey] => monkey )
//获取hash中key的数量
echo $redis->hlen(&＃39;hash&＃39;);echo &＃39;
&＃39;;
 // 4
//删除hash中一个key 如果表不存在或key不存在则返回false
echo $redis->hdel(&＃39;hash&＃39;, &＃39;dog&＃39;);echo &＃39;
&＃39;;
var_dump($redis->hdel(&＃39;hash&＃39;, &＃39;rabbit&＃39;));echo &＃39;
&＃39;;
// 1
// int(0)

5 redis 操作 Set (集合):

connect(&＃39;127.0.0.1&＃39;, 6379);
//集合
// 添加一个元素
echo $redis->sadd(&＃39;set&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;         // 1
echo $redis->sadd(&＃39;set&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;         // 0
echo $redis->sadd(&＃39;set&＃39;, &＃39;dog&＃39;);echo &＃39;
&＃39;;        // 1
echo $redis->sadd(&＃39;set&＃39;, &＃39;rabbit&＃39;);echo &＃39;
&＃39;;     // 1
echo $redis->sadd(&＃39;set&＃39;, &＃39;bear&＃39;);echo &＃39;
&＃39;;      // 1
echo $redis->sadd(&＃39;set&＃39;, &＃39;horse&＃39;);echo &＃39;
&＃39;;    // 1
// 查看集合中所有的元素
$set = $redis->smembers(&＃39;set&＃39;);
print_r($set);echo &＃39;
&＃39;;
// Array ( [0] => rabbit [1] => cat [2] => bear [3] => dog [4] => horse )
//删除集合中的value
echo $redis->srem(&＃39;set&＃39;, &＃39;cat&＃39;);echo &＃39;
&＃39;;    // 1
var_dump($redis->srem(&＃39;set&＃39;, &＃39;bird&＃39;));echo &＃39;
&＃39;;     // int(0)
$set = $redis->smembers(&＃39;set&＃39;);
print_r($set);echo &＃39;
&＃39;;
// Array ( [0] => dog [1] => rabbit [2] => horse [3] => bear )
//判断元素是否是set的成员
var_dump($redis->sismember(&＃39;set&＃39;, &＃39;dog&＃39;));echo &＃39;
&＃39;;     // bool(true)
var_dump($redis->sismember(&＃39;set&＃39;, &＃39;bird&＃39;));echo &＃39;
&＃39;;    // bool(false)
//查看集合中成员的数量
echo $redis->scard(&＃39;set&＃39;);echo &＃39;
&＃39;;    // 4
//移除并返回集合中的一个随机元素(返回被移除的元素)
echo $redis->spop(&＃39;set&＃39;);echo &＃39;
&＃39;;  // bear
print_r($redis->smembers(&＃39;set&＃39;));echo &＃39;
&＃39;;   
 // Array ( [0] => dog [1] => rabbit [2] => horse )
connect(&＃39;127.0.0.1&＃39;, 6379);
//集合
$redis->sadd(&＃39;set&＃39;, &＃39;horse&＃39;);
$redis->sadd(&＃39;set&＃39;, &＃39;cat&＃39;);
$redis->sadd(&＃39;set&＃39;, &＃39;dog&＃39;);
$redis->sadd(&＃39;set&＃39;, &＃39;bird&＃39;);
$redis->sadd(&＃39;set2&＃39;, &＃39;fish&＃39;);
$redis->sadd(&＃39;set2&＃39;, &＃39;dog&＃39;);
$redis->sadd(&＃39;set2&＃39;, &＃39;bird&＃39;);
print_r($redis->smembers(&＃39;set&＃39;));echo &＃39;
&＃39;;
 // Array ( [0] => cat [1] => dog [2] => bird [3] => horse )
print_r($redis->smembers(&＃39;set2&＃39;));echo &＃39;
&＃39;;
// Array ( [0] => bird [1] => dog [2] => fish )
//返回集合的交集
print_r($redis->sinter(&＃39;set&＃39;, &＃39;set2&＃39;));echo &＃39;
&＃39;;
// Array ( [0] => dog [1] => bird )
//执行交集操作 并结果放到一个集合中
$redis->sinterstore(&＃39;output&＃39;, &＃39;set&＃39;, &＃39;set2&＃39;);
print_r($redis->smembers(&＃39;output&＃39;));echo &＃39;
&＃39;;
// Array ( [0] => dog [1] => bird )
//返回集合的并集
print_r($redis->sunion(&＃39;set&＃39;, &＃39;set2&＃39;));echo &＃39;

print_r($redis->smembers(&＃39;output&＃39;));echo &＃39;
&＃39;;
// Array ( [0] => horse [1] => cat )
