批量订阅 redis的psubscribe支持通过模式匹配的方式实现批量订阅,订阅方式 回调函数写函数名或者redis->psubscribe(['my*'],array(new TestCall(),...'psubscribe')); //回调函数为类中的方法,类名写你自己定义的类 subscribe.php <?...(['my*'],'psubscribe'); //匹配方式2:发布可用$redis->publish('mydest','this is a message'); //$redis->psubscribe...','this is a message'); $redis->psubscribe(['my[ae]est'],'psubscribe'); function psubscribe($redis,...(['my[ae]est'],'psubscribe');返回数量为1,$redis->subscribe(['chan'],'callback'); 这种方式获取不到,因此返回数量为0 参考:
