json-patch-php

Produce and apply json-patch objects.

Implements the IETF json-patch and json-pointer drafts:

http://tools.ietf.org/html/draft-ietf-appsawg-json-patch-02

http://tools.ietf.org/html/draft-ietf-appsawg-json-pointer-02

Entry points

• get($doc,$pointer) - get a value from a json document
• diff($src,$dst) - return patches to create $dst from$src
• patch($doc,$patches) - apply patches to $doc and return result

Arguments are PHP arrays, i.e. the output of json_decode($json_string, 1)

All structures are implemented directly as PHP arrays. An array is considered to be 'associative' (e.g. like a JSON 'object') if it contains at least one non-numeric key.

Because of this, empty arrays ([]) and empty objects ({}) compare the same, and (for instance) an 'add' of a string key to an empty array will succeed in this implementation where it might fail in others.
