To parse the JSON, try using PHP's json_decode function. http://php.net/manual/en/function.json-decode.php

I can't give you specifics on how to store it in the database without knowing what type of database it is, but you probably should use PHP's PDO (PHP Data Object) API. (http://php.net/manual/en/book.pdo.php) It lets you prepare and execute queries/insertions/commands just like you can the database's shell.
