Is JSON.stringify( ) equivalent to serialization or effectively serialization or is it just a necessary step towards serialization?

  1. Summary: in this tutorial, you will learn how to control the execution flow of statements. The sqlite3 module provides you with two methods for controlling the execution flow of statements. The serialize method allows you to execute statements in serialized mode, while the parallelize method executes the statements in parallel. Let’s look into each method.
  2. JavaScript tool to unserialize data taken from PHP. It can parse 'serialize' output, or even serialized sessions data. The PHP unserializer is taken from kvz's phpjs project. The session unserializer's idea is taken from dumpling, which is highly limited by its lack of a real unserializer, and has lot of crash cases.

In other words, is JSON.stringify( ) sufficient but not necessary for serialization? Or is necessary but not sufficient? Or is it neither necessary nor sufficient for serialization of JavaScript objects?

If you’d like your project listed, send a pull request. Note: This specification marked 1.0. MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON. In this article you will learn about serialization and deserialization In C#. A good place to start is the Codec Engine Category.

Serialization is the act of converting data into a format that can be written to disk or transmitted over the network (or written on paper if that's what you want). Usually, serialization is transforming objects to text but that's not necessary since there are several serialization formats such as bittorrent's bencoding and the old/ancient standard asn.1 formats are binary.

JSON is one form of text-based serialization format and is currently very popular due to it's simplicity. It's not the only one though. Other popular formats include XML and CSV.

Php Serialize To Json

Due to its popularity and its origin as javascript object literal syntax ES5 introduced JSON.stringify() to generate a JSON string from an object. Previously you had to use libraries or write a recursive descent parser to do the job.

So, is JSON.stringify() enough for serialization? Yes, if the output format you want is JSON. No, if you want other output formats such as XML or CSV or bencode.

There are limitations to the JSON format. One limitation is that JSON cannot encode functions so JSON.stringify() ignores functions/methods when serializing. JSON also can't encode circular references. Most other serialization formats have this limitation as well but since JSON looks like javascript syntax some people assume it can do what javascript object literals can. It can't.

So the relationship between 'JSON' and 'serialization' is like the relationship between 'Toyota Prius' and 'car'. JSON.stringify() is simply a function that generates JSON strings so I guess that would make it a Toyota factory.

Old question, but the following information may be useful for posterity.

Of course, you can serialise any way you want, including any number of custom methods, but JSON has become an increasingly popular method.

The most obvious benefit of JSON is that it represents objects in the same way that JavaScript object literals do, though it is slightly less flexible. Nevertheless, if you can represent normal data in JavaScript then JSON is a good match.

The most significant feature is that, since it represents objects as well as arrays, it can represent fairly complex & hierarchical data.

For one reason or another, JSON has more-or-less supplanted XML as the preferred serialisation for sending data between the server and browser. It is so useful that many languages include their own JSON functions (PHP, for example, has the better named json_encode & json_decode functions), as do some modern Databases. I myself have found it convenient to use JSON functions to store a more complex data structure in a single field of a database without JavaScript anywhere in sight).

The short answer is yes, for the most part it is a sufficient step to serializing most data (non-binary). It is not, however, necessary as there are alternatives.

Serializing binary data, on the other hand, now that’s another story …

Short answer.. Serialize means the same thing as Stringify, IMHO.

This question already has an answer here:

  • How do I PHP-unserialize a jQuery-serialized form? 13 answers

I have the following code when a user clicks in the 'generate' element the data within the form 'serializeData' is serialized in js. This string is passed to the loadTemplate function which in turn POST's that string with other variables to a php script for processing.

What I'm looking for is a way to unserialize the js string in PHP or best practice for getting at the data, here is an example output of the serilized data as seen in PHP as a string: -

input1=meeting&input2=select+date&input3=enter+text&input4=NUMBER+MISSING

The serialized form data is passed to PHP in the loadTemplate function in the userData variable.

Functions: -

Any thoughts?
