前言

php反序列化的字符逃逸算是比较难理解的一个知识点，在最近的好几场比赛中都出现了相关的题，于是下定决心彻底理解透彻这个知识点，于是便有了这篇文章。

本文涉及知识点实操练习——PHP反序列化漏洞实验：通过本次实操，大家将会明白什么是反序列化漏洞，反序列化漏洞的成因以及如何挖掘和预防此类漏洞。

基础知识理解

字符逃逸在理解之后就能够明白，这是一种闭合的思想，它类似SQL中的万能密码，理解这种原理之后会变得特别容易。

在SQL注入中，我们常用'、"来对注入点进行一些闭合或者一些试探，从而进行各种姿势的注入，反序列化时，序列化的值是以;作为字段的分隔，在结尾是以}结束，我们稍微了解一下，
