最近阅读tp5的底层类的实现,
看到了大神的Redis 类的实现, 觉
得非常的简洁明了,而且统一了所有的get,set,在更新一下,非常值得参考

// 检测是否为JSON数据 true 返回JSON解析数组, false返回源数据
return (null === $jsonData) ? $value : $jsonData;

16.11.9号更新:
后来发现,由于redis存储数据方式,如果存储的数据中有"x:x"时,似乎会导致读取错误,存储时需注意
今天遇到了redis保存多维数组出错的情况,得知redis是只能模拟简单数组,没有多维数组的数据结构.
解决方案是序列化一下保存的数据
我的解决方案是在原有的hset跟hget的基础上新增了两个方法 setArr跟getArr 调用 hset hget 用来保存多维数组的情况
这两个方法是在存之前,取之后都进行序列化操作.
既不影响原来的简单操作
又实现了保存多维数组的作用
例子如下
<?php
namespace Vendor\Redis;
class DefaultRedis{
private $redis;
public function __construct($host='127.0.0.1',$port =3198,$auth = '#yr9XjB%b6k'){
$this->redis = new \Redis();
$this->redis->pconnect($host,$port);
$this->redis->auth($auth);
}
