Usage

<?php

// Get the schema and data as objects
$retriever = new JsonSchema\Uri\UriRetriever;
$schema = $retriever->retrieve('file://' . realpath('schema.json'));
$data = json_decode(file_get_contents('data.json'));

// If you use $ref or if you are unsure, resolve those references here
// This modifies the $schema object
$refResolver = new JsonSchema\RefResolver($retriever);
$refResolver->resolve($schema, 'file://' . __DIR__);

// Validate
$validator = new JsonSchema\Validator();
$validator->check($data, $schema);

if ($validator->isValid()) {
    echo "The supplied JSON validates against the schema.\n";
} else {
    echo "JSON does not validate. Violations:\n";
