get-zen/json-patch-php

Produce and apply json-patch objects. Forked from mikemccabe/json-patch-php (https://github.com/mikemccabe/json-patch-php). THIS FORK adds an `ensure` operation that sets a value at a given path, creating any missing intermediate structure (deep upsert semantics). Just set the damned field!

README

Forked from mikemccabe/json-patch-php.

Produce and apply json-patch objects.

Implements IETF JSON-patch (RFC 6902) and JSON-pointer (RFC 6901):

http://tools.ietf.org/html/rfc6902 http://tools.ietf.org/html/rfc6901

Extensions

Adds custom ensure operation (op) that replaces the value at target path or creates it if the path does not exist. (alpha!!! works in production, no angry customers so far)

Using with Composer

composer require get-zen/json-patch-php

Then, in your project's code, use the JsonPatch class definition from the GetZen namespace like so:

use GetZen\JsonPatch;

Entry points

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

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

(Note that you MUST pass 1 as the second argument to json_decode to get an array. This library does not work with stdClass objects.)

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.

$simplexml_mode is provided to help with working with arrays produced from XML in the style of simplexml - e.g. repeated XML elements are expressed as arrays. When $simplexml_mode is enabled, leaves with scalar values are implicitly treated as length-1 arrays, so this test will succeed:

{ "comment": "basic simplexml array promotion",
  "doc": { "foo":1 },
  "patch": [ { "op":"add", "path":"/foo/1", "value":2 } ],
  "expected": { "foo":[1, 2] } },

Also, when $simplexml_mode is true, 1-length arrays are converted to scalars on return from patch().

Tests (!!!! Not maintained)

Some tests are in a submodule (https://github.com/json-patch/json-patch-tests). Do 'git submodule init' to pull these, then 'php runtests.php' to run them.
