JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages (C, C++, JavaScript, etc). These properties make JSON an ideal data-interchange language. JSON has two primary parts: 1. A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array. 2. An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence. These are universal data structures. Virtually all modern programming languages support them in one form or another. It makes sense that a data format that is interchangeable with programming languages also be based on these structures.
There are a few different ways to parse JSON data in PHP. The most popular methods are to use the built-in functions json_decode() and json_encode(), or to use the third-party library JsonSerializable.
Overall, PHP has many built-in functions that allow developers to work with JSON data. In addition, there are many third-party libraries that can be used to parse and manipulate JSON data. With so many options available, there is no excuse not to be able to work with JSON data in PHP.
