phpwind数据库的job表中,有个reward字段,保存的字符串似乎是一种json格式,但我没见过这种格式,请问怎么用,有何优点?
似乎是任务执行后的规则配置,代码如下:
a:4:{s:4:"type";s:5:"money";s:3:"num";s:2:"10";s:8:"category";s:6:"credit";s:11:"information";s:17:"可获得 铜币 ";}
------解决方案--------------------
序列化后的。存储方便。
------解决方案--------------------
这是 php 序列化后的串,用 serialize 函数生成的
可用 unserialize 函数还原
示例的数据是一个用4个元素的关联数组,肯定是不能直接放在数据库中的
序列化的作用就是将复杂的数据结构转换成简单的字符串,这样就便于保存了
------解决方案--------------------
正解,用unserialize可以还原

Serialization is the process of converting a data structure or object into a string for storage, transmission, or representation, and conversely, parsing a string into the original data structure or object. In PHP, we can use the serialize() function to serialize a variable into a string, and use the unserialize() function to deserialize a string into a primitive data structure or object. This article will focus on the use and precautions of the PHPunserialize() function. 1. unserialize

PHP is a popular programming language commonly used for web development. Among them, serialize and unserialize are two very useful functions that can convert PHP objects into strings and deserialize them.

In PHP, sometimes you need to convert objects or arrays into strings for storage or transmission. This process is called serialization, which converts the data structure into a sequence of strings so that the data can be transmitted and stored in different environments. PHP provides a built-in function serialize() that can implement serialization quickly and conveniently. 1. Serialization of arrays For an array, you can use serialize() to serialize it into a string. Here's an example. $arr=['apple
