I write my own code for several projects now, open redis, get data into variables, then open mysqli, insert data into the database, and then add this script to cron.
I feel like there is a lot of repetitive code here, so I would like to ask if there are some common and efficient excellent frameworks in the industry for persistently storing data in redis to mysql?

1. First of all, even if you choose a framework, what it does is to take it out from redis and then persist it to mysql. It does not reduce the operations of the data layer, but the framework does it for you without having to write it in your code. (An advantage only).
2. Data structure and persistence. The format of Redis storage is mostly K-V. Key is usually the primary key ID, and VALUE is usually JSON. What about mysql? Mysql is a field, that is, Json still needs to be converted into javabean and then persisted. So if your data structure is fixed, you can consider writing a script for regular processing. If your data changes, then you should control it manually. Otherwise, what is the difference between changing your script and writing 2 more lines of code?
Summary: The framework cannot solve your problem of adapting the complex data format from redis to mysql. It would be nice if it was just a simple data structure that maintained a timer. Why go to extra trouble and cause trouble? If a bug occurs, it may not be controllable.
Persistent storage of data in redis
into mysql
is not recommended by me. redis
is used as a cache, and the data comes from the data persistence layer.
If it is a search engine, such as solr
and mysql
, in this case, you can consider persisting data to the database.

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

查找方法:1、用strpos(),语法“strpos("字符串值","查找子串")+1”;2、用stripos(),语法“strpos("字符串值","查找子串")+1”。因为字符串是从0开始计数的,因此两个函数获取的位置需要进行加1处理。
