The usage of serialize () and unserialize () in php

This article introduces the knowledge of "serialize() and unserialize() usage in php". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

serialize() and unserialize() are explained in the PHP manual as:

serialize - Generates a storable representation of a value

serialize -generates a representation of a storable value

unserialize - Creates a PHP value from a stored representation

unserialize -Create PHP values from stored representations

Obviously, the interpretation of "a stored representation" translated into a storable value is still very confusing.

If the language is not clear enough, then we can learn the purpose of these two functions with a concrete PHP example.

We can also replace the objects in the example with arrays and other types, and the effect is the same!

Serialize() is a method of serializing the values of PHP variables such as objects, arrays, etc. into strings and storing them. Serialized strings can be stored elsewhere, such as in databases, sessions, cookies, etc., without losing the type and structure of these values. This way, the data for these variables can be passed between PHP pages and even between PHP programs.
