PHP and JSON

PHP and JSON are often used together for web development, especially when you're building APIs or handling data exchange between a server and a client.

Here's a quick overview and example of how they work together:

What is JSON?

• JSON (JavaScript Object Notation) is a lightweight data-interchange format.

• It's easy to read/write for humans and easy to parse/generate for machines.

• Format example:

  { "name": "Alice", "age": 30, "is_member": true }

Working with JSON in PHP

1. Encoding PHP data into JSON

Use json_encode() to convert PHP arrays or objects to JSON format.

2. Decoding JSON into PHP

Use json_decode() to convert JSON into a PHP variable.

Common Use Case: API Response
