JSON Patch for PHP

This is an implementation of JSON Patch written in PHP.

Installation via Composer

$ composer require php-jsonpatch/php-jsonpatch

Usage

Now you can use JSON Patch for PHP via the available Composer autoload file.

Patch operations are defined in JSON and bundled in an array. Available JSON Patch operations are add, remove, replace, move, copy, and test; if their mandatory properties are not set a Rs\Json\Patch\InvalidOperationException will be thrown.

If necessary you can disable some patch operations by setting a whitelist bitmask in the constructor e.g. $patch = new Patch($targetDocument, $patchDocument, Add::APPLY | Copy::APPLY | Replace::APPLY | Remove::APPLY);. This will not allow the usage of the move and test patch operation from the patch document. If used, these operations are just ignored. The default is to allow all patch operations.

<?php require_once 'vendor/autoload.php';

use Rs\Json\Patch;
use Rs\Json\Patch\InvalidPatchDocumentJsonException;
use Rs\Json\Patch\InvalidTargetDocumentJsonException;
use Rs\Json\Patch\InvalidOperationException;

try {
    $targetDocument = '{"a":{"b":["c","d","e"]}}';

    $patchDocument = '[
        {"op":"add", "path":"/a/d", "value":["a","b"]}, // {"a":{"b":["c","d","e"],"d":["a","b"]}}
        {"op":"test", "path":"/a/d/-", "value":"b"}, // previous target document
        {"op":"remove", "path":"/a/d/-"}, // {"a":{"b":["c","d","e"],"d":["a"]}}
        {"op":"test", "path":"/a/d/-", "value":"a"}, // previous target document
        {"op":"add", "path":"/a/d/-", "value":"b"}, // {"a":{"b":["c","d","e"],"d":["a","b"]}}
        {"op":"test", "path":"/a/d", "value":["a","b"]}, // previous target document
        {"op":"move", "path":"/a/c", "from":"/a/d"}, // {"a":{"b":["c","d","e"],"c":["a","b"]}}
        {"op":"test", "path":"/a/c", "value":["a","b"]}, // previous target document
        {"op":"copy", "path":"/a/e", "from":"/a/c"}, //   {"a":{"b":["c","d","e"],"c":["a","b"],"e":["a","b"]}}
        {"op":"test", "path":"/a/e", "value":["a","b"]}, // previous target document
        {"op":"replace", "path":"/a/e", "value":["a"]}, // {"a":{"b":["c","d","e"],"c":["a","b"],"e":["a"]}}
        {"op":"test", "path":"/a/e", "value":["a"]} // previous target document
    ]';

    $patch = new Patch($targetDocument, $patchDocument);
    $patchedDocument = $patch->apply(); // {"a":{"b":["c","d","e"],"c":["a","b"],"e":["a"]}}
} catch (InvalidPatchDocumentJsonException $e) {
    // Will be thrown when using invalid JSON in a patch document
} catch (InvalidTargetDocumentJsonException $e) {
    // Will be thrown when using invalid JSON in a target document
} catch (InvalidOperationException $e) {
    // Will be thrown when using an invalid JSON Pointer operation (i.e. missing property)
}
