Example Analysis of JSON Array and object in PHP

This article will explain in detail the example analysis of JSON arrays and objects in PHP. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

In the process of data interaction between the PHP backend and the client, sometimes the format of the JSON data is irregular, sometimes an array, then an object, which makes the client developer feel like he is about to collapse.

Therefore, the most important link is the necessary understanding of the json_encode function principle of PHP by the relevant personnel at the front and back end.

Array in PHP is an omnipotent data structure, unlike other languages that define many constrained data types to describe the structure according to the required scenarios, so it is difficult for PHP programmers to explain to the client staff what structure of data is returned.

It becomes a situation where the array data of PHP is encoded into json, but the output value is sometimes an array, sometimes an object.
