This library provides JSON schema validation using the schema found at http://json-schema.org. Note that it is not yet feature complete, but does support basic validation. The JSON schema draft can be found at http://tools.ietf.org/html/draft-zyp-json-schema-03

Requirements

• PHP 5.3 or greater (requires namespace and closure support)

Usage

The standard way to use the JSON Validator is by passing in the location on your server to the JSON schema and validating against it, like so:

$someJson = '{"foo":"bar"}';
$jsonObject = json_decode($someJson);

$validator = new Validator('/path/to/yourschema.json');
$validator->validate($jsonObject);

Alternatively you can pass in the raw JSON schema directly to the constructor:

$myRawJsonSchema = "{...}";
$someJson = '{"foo":"bar"}';
$jsonObject = json_decode($someJson);

$validator = new Validator($myRawJsonSchema, "json");
$validator->validate($jsonObject);
