本篇文章给大家分享的内容是php 加 redis 入门及简单应用 ，有着一定的参考价值，有需要的朋友可以参考一下
一、实验环境： win10 + redis3.2 + php7
二、php-redis / redis /redis图形管理工个等安装，此步骤略过；
三、redis常用的五种数据类型，不做详细说明
参考：http://www.runoob.com/redis/r...
四、php + mysql + redis 简单应用
数据库名称：redis 数据表：redis_user
模拟 php 操作Mysql + redis 的 CURD 操作
1、config.php配置文件
array(
'host'=>'127.0.0.1',
'user'=>'root',
'pass'=>'root',
'dbname'=>'redis',
'prefix'=>'redis_'
),
'redis'=>array(
'host'=>'127.0.0.1',
'port'=>6379
)
);index.php 入口文件，操作Mysql时请使用主键ID
table('user')->insert(['user'=>'张三','pass'=>md5('123456'),'create_time'=>date('Y-m-d H:i:s')]);
//删除数据
// echo Mysql::getInstance()->table('user')->where(array('id'=>30))->delete();
//查看单条数据
// $data = Mysql::getInstance()->table('user')->where(array('id'=>'30'))->find();
// print_r($data);
//查找所有数据
// $all = Mysql::getInstance()->table('user')->field('id,user')->select();
$all = Mysql::getInstance()->table('user')->select();
print_r($all);
//修改数据
// echo Mysql::getInstance()->table('user')->where(array('id'=>30))->update(['user'=>'张三adfadfasdf11111111','pass'=>md5('123456aaa')]);
