A complete list of redis commands under PHP-PHP Tutorial-php.cn

This article mainly introduces the complete list of redis commands under PHP, which has certain reference value. Now I share it with you. Friends in need can refer to it

redis Using
application scenario cache, queue, data storage, acting on memory, it is easier to lose

##$user=User::all()-> toarray();

string type can only be a single string, not an array

set
添加
Redis::set(&#39;number&#39;, 1);
Redis::append(&#39;number&#39;,2);
//追加的
dd(Redis::strlen(&#39;number&#39;));
//返回字符的长度
get
获取值
dd(redis::get(&#39;nember&#39;));
getset 
先获取,完后设置该值
dd(redis::getset(&#39;nember&#39;,&#39;baidu123&#39;));
incr 
适合做计数器
Redis::incr(&#39;number&#39;);
Redis::incrBy(&#39;number&#39;,3);
//直接加3
incrByFloat 
浮点数字直接加1.5
Redis::set(&#39;number&#39;, 1);
dd(redis::incrByFloat(&#39;number&#39;,0.03));
exists 
判断键值是否存在
dd(redis::exists(&#39;key&#39;)); 
//存在是1，不存在是0
mset mget 
批量操作
Redis::set(&#39;d&#39;, 555);
redis::mset([&#39;a&#39;=>1,&#39;b&#39;=>2,&#39;c&#39;=>3]);
print_r(redis::mget([&#39;a&#39;,&#39;b&#39;,&#39;c&#39;,&#39;d&#39;]));
//Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 555 )

list type (list push pop llen)

lpus 
添加左到右面
redis::del(&#39;la&#39;);
redis::lpush(&#39;la&#39;,1);
redis::lpush(&#39;la&#39;,2);
redis::lpush(&#39;la&#39;,3);
dd(redis::lrange(&#39;la&#39;,0,6));
//展示la从0到6
rpush  添加右到左面
redis::rpush(&#39;ra&#39;,1);
redis::rpush(&#39;ra&#39;,2);
redis::rpush(&#39;ra&#39;,3);
dd(redis::lrange(&#39;ra&#39;,0,6));
dd(redis::lindex(&#39;ra&#39;,0));
//获取健的值
linsert  在列中插入（这里面的3是只第一个）
redis::linsert(&#39;ra&#39;,"BEFORE",&#39;3&#39;,&#39;555&#39;);
//在ra队列中在3之前插入555
redis::linsert(&#39;ra&#39;,"AFTER",&#39;3&#39;,&#39;666&#39;);
//在ra队列中在3之后插入666
dd(redis::lrange(&#39;ra&#39;,0,-1));
lpop  返回并删除列表的第一个元素(队列或秒杀)
echo(redis::lpop(&#39;ra&#39;));
dd(redis::lrange(&#39;ra&#39;,0,-1));
rpop  返回并删除列表的最后一个元素(队列或秒杀)
echo(redis::rpop(&#39;ra&#39;));
//返回空则列表为空
dd(redis::lrange(&#39;ra&#39;,0,-1));
blpop brpop 消息队列
redis::lpush(&#39;a&#39;,54);
redis::brpop(&#39;a&#39;,0);
//第二个参数是时间 0是永不阻塞
dd(redis::lrange(&#39;a&#39;,0,-1));
如果列表存在，则将字符串值添加到列表头（左侧）
redis::lpush(&#39;la&#39;,5);
redis::lpushx(&#39;la&#39;,6);
//右侧是rpush
redis::lpush(&#39;la&#39;,8);
dd(redis::lrange(&#39;la&#39;,0,-1));
lrem  删除指定的键值
redis::lrem(&#39;ra&#39;,6,1);
//lrem(&#39;ra&#39;,6,1) 删除左到右6个1
redis::lrem(&#39;ra&#39;,-1,1);
//lrem(&#39;ra&#39;,-1,1) 删除右到左1个1
redis::lrem(&#39;ra&#39;,0,1);
//lrem(&#39;ra&#39;,0,1) 删除全部1
dd(redis::lrange(&#39;ra&#39;,0,-1));
lset 修改 使用新值在索引处设置列表。
redis::lset(&#39;la&#39;,0,&#39;aaaa&#39;);
dd(redis::lrange(&#39;la&#39;,0,-1));
ltrim 修剪现有列表 类似与php substr
redis::ltrim(&#39;la&#39;,0,2);
dd(redis::lrange(&#39;la&#39;,0,-1));
llen 列表的长度
dd(redis::llen(&#39;la&#39;));
从列表的尾部弹出一个值，并将其推到另一个列表的前面。同样返回这个值
redis::rPopLPush(&#39;la&#39;,&#39;ra&#39;);
//将la的尾部，推送到列表的前面
一般用户队列防止丢失

redis::sadd(&#39;sb&#39;,2);
redis::sadd(&#39;sb&#39;,3);

dd(redis::sdiff(&#39;sa&#39;,&#39;sb&#39;));

smembers 随机删除
redis::spop(&#39;sb&#39;);
dd(redis::smembers(&#39;sb&#39;));
srem 指定删除
redis::srem(&#39;sb&#39;,2);
//在集合sb中删除2的值
dd(redis::smembers(&#39;sb&#39;));
sinter 判断两个集合之间的交集
dd(redis::sinter(&#39;sa&#39;,&#39;sb&#39;));
执行几个集合的交集，并保存为新的集合
redis::sInterStore(&#39;sc&#39;,&#39;sa&#39;,&#39;sb&#39;);
//sa和sb的交集，存于sc中
dd(redis::sMembers(&#39;sc&#39;));
//输出一个集合
将指定成员从srcKey中的集合移至dstKey处的集合
redis::smove(&#39;sa&#39;,&#39;sb&#39;,1);
//把sa中的1移到sb中
dd(redis::smembers(&#39;sb&#39;));
返回多个集合的联合
dd(redis::sUnion(&#39;sa&#39;,&#39;sb&#39;));
返回联合，并存于一个集合中
redis::sUnionStore(&#39;sd&#39;,&#39;sa&#39;,&#39;sc&#39;);
//把sa和sc的联合返回与sd中

1. Master-slave mode

在redis.conf中，添加slaveof ip 端口 可作为从redis，只能读取与同步
slaveof <masterip> <masterport>

Copy after login

2. The pipeline mode of redis is large When executing files with data, use this value transfer to reduce time

redis::multi()

Copy after login

3. Message publishing and subscription
