我有一个 php 脚本，其中我必须执行多个偶尔查询。所以，我想知道什么是连接和执行redis查询的最佳方式。
单向，连接一次，保持连接活动，从脚本开始到结束执行所有查询，然后关闭连接

//Request comes and some work is done on the request like validation etc
//then
$redis = new Redis()->pconnect();   
$redis->hMSet();

//Some other codes are run like sending email or similar <-Long Codes
//then
$redis->hSet();

//If everything was good send updates to other users <-Long Codes
//then
$redis->setBit();

//Some More Work <-Long Codes
//then
$redis->hGet();
$redis->close();

双向，为每个redis操作创建连接，并为每个操作关闭和重复

//Request comes and some work is done on the request like validation etc
//then
$redis = new Redis()->pconnect();   
$redis->hMSet();
$redis->close();

//Some other codes are run like sending email or similar <-Long Codes
//then
$redis = new Redis()->pconnect();   
$redis->hSet();
$redis->close();

//If everything was good send updates to other users <-Long Codes
//then
$redis = new Redis()->pconnect();   
$redis->setBit();
$redis->close();

//Some More Work <-Long Codes
//then
$redis = new Redis()->pconnect();   
$redis->hGet();
$redis->close();

第一个似乎更好，但我在想，如果它可能是一个坏的做法，保持连接活着，而运行其他代码。这一切都是因为redis能够高效地处理每秒数百万个请求，而我的任何错误都不会导致某些结果。我读到创建一个连接是资源密集型的，但我想确定更好的方法。
