Connect Redis

# 实例化$redis = new Redis();
# 连接redisredis->connect('127.0.0.1',6379);

String

# 设置$redis->set('abc',123);
# 提取$redis->get('abc');

List(list):

# 左边加入数据
$redis->lpush('language','PHP');
$redis->lpush('language','Java');
$redis->lpush('language','Go');
$redis->lpush('language','Python);

# 循环获取值
$languages = $redis->lrange('language',0,-1);
print_r($languages);
echo &#39;<hr/>&#39;;

# 右侧加入一条数据
$redis->rpush(&#39;language&#39;,&#39;C&#39;);
$languages = $redis->lrange(&#39;language&#39;,0,-1);
print_r($languages);
echo "<hr/>";

# 左边弹出数据
$redis->lpop(&#39;language&#39;);
$languages = $redis->lrange(&#39;language&#39;,0,-1);
print_r($languages);
echo "<hr/>";

# 右边弹出
$redis->rpop(&#39;language&#39;);
$languages = $redis->lrange(&#39;language&#39;,0,-1);
print_r($languages);
echo "<hr/>";

# 获取list长度
$length = $redis->lsize(&#39;language&#39;);
echo $length; echo &#39;<hr/>&#39;;

# 获取列表中key位置的值
echo $redis->lget(&#39;language&#39;,2);
echo $redis->lindex(&#39;language&#39;,2);

# 设置列表的key位置的值
$redis->lset(&#39;language&#39;,2);

# 返回从start到end的值
$redis->lrange(&#39;language&#39;,0,2);
$redis->lgetrange(&#39;language&#39;,0,2);

# 截取链表中start到end的元素,保留截取的元素,其余的删除
$res = $redis-> ltrim(&#39;language&#39;,0,1);
print_r($res);echo &#39;<br/>&#39;;
print_r($redis->lrange(&#39;language&#39;,0,-1));

# 删除方式: 从左向右删
$redis->lrem(&#39;language&#39;,&#39;PHP&#39;,2);

# 删除方式: 从右向左删
$redis->lrem(&#39;language&#39;,&#39;Go&#39;,2);

# 删除所有
$redis->lrem(&#39;language&#39;,&#39;PHP&#39;,0);

Hash(Hash)

# 给Hash的key设置value,成功返回1 失败返回0
echo $redis->hset('person','name','Miki');
echo &#39;<br/>&#39;;
echo $redis->hset(&#39;person&#39;,&#39;age&#39;,&#39;18&#39;);
echo &#39;<br/>&#39;;
echo $redis->hset(&#39;person&#39;,&#39;gender&#39;,&#39;female&#39;);
echo &#39;<br/>&#39;;

# 获取hash中某个key的值
echo $redis->hget(&#39;person&#39;,&#39;name&#39;);

# 获取所有的keys
$arr = $redis->hkeys(&#39;person&#39;);
print_r($arr);echo &#39;<br/>&#39;;

# 获取hash中的所有值,注意:顺序随机!$arr = $redis->hvals(&#39;person&#39;);
print_r($arr);echo &#39;<br/>&#39;;
