Answer
json_encode() converts arrays/objects to JSON; json_decode() converts JSON strings back to PHP structures.
Quick Answer
json_encode() converts PHP arrays/objects into a JSON string. json_decode() parses a JSON string into PHP objects or arrays (pass true as second arg for arrays). Returns null on failure. Check json_last_error() for error details. Used heavily for API responses. JSON is the standard data format for REST APIs and config files.
