README
This is an implementation of JSON Pointer written in PHP. Triggered by @janl's node.js implementation and being a bit bored.
Installation via Composer
$ composer require softinvest/php-jsonpointer
Usage
Now you can use JSON Pointer for PHP via the available Composer autoload file.
<?php require_once 'vendor/autoload.php'; use SoftInvest\Json\Pointer; use SoftInvest\Json\Pointer\InvalidJsonException; use SoftInvest\Json\Pointer\NonexistentValueReferencedException; $invalidJson = '{"Missing colon" null}'; try { $jsonPointer = new Pointer($invalidJson); } catch (InvalidJsonException $e) { $message = $e->getMessage(); // Cannot operate on invalid Json. Message: Parse error on line 1: ... } $json = '{"foo":1,"bar":{"baz":2},"qux":[3,4,5],"m~n":8,"a/b":0,"e^f":3}'; $jsonPointer = new Pointer($json); try { $all = $jsonPointer->get(""); // string('{"foo":1,"bar":{"baz":2},"qux":[3,4,5],"m~n":8,"a/b":0,"e^f":3}') $one = $jsonPointer->get("/foo"); // int(1) $two = $jsonPointer->get("/bar/baz"); // int(2) $three = $jsonPointer->get("/qux/0"); // int(3) $four = $jsonPointer->get("/qux/1"); // int(4) $five = $jsonPointer->get("/qux/-"); // int(5) $five = $jsonPointer->get("/qux/" . Pointer::LAST_ARRAY_ELEMENT_CHAR); // int(5) $zero = $jsonPointer->get("/a~1b"); // int(0) $eight = $jsonPointer->get("/m~0n"); // int(8) $three = $jsonPointer->get("/e^f"); // int(3) $nonexistent = $jsonPointer->get("/qux/7"); } catch (NonexistentValueReferencedException $e) { $message = $e->getMessage(); // Json Pointer '/qux/7' reference a nonexistent value }
