Answer 1

In their example, they're creating a JsonValidator object.
This is different from the actual namespace of the class, which is Json\Validator.
Try dropping use Json\Validator as JsonValidator at the top of your file so that you're able to refer to the class the same way the docs do.
I'd expand their docs from:
$someJson = '{"foo":"bar"}';
$jsonObject = json_decode($someJson);
$validator = new JsonValidator('/path/to/yourschema.json');
$validator->validate($jsonObject);
To
<?php
namespace Your\Domain;
use Json\Validator as JsonValidator;
require_once('./vendor/autoload.php');
$someJson = '{"foo": "bar"}';
$jsonObject = json_decode($someJson);
$validator = new JsonValidator('/path/to/yourschema.json');
$validator->validate($jsonObject);
Alternatively, you could substitute new JsonValidator('/path/to/yourschema.json') for new Json\Validator('/path/to/yourschema.json').
Edit: By the way - you might find the example schemas at json-schema.org helpful when using this library.
Here's the main one from that link:
{
"title": "Example Schema",
"type": "object",
"properties": {
"firstName": {
"type": "string"
},
"lastName": {
"type": "string"
},
"age": {
"description": "Age in years",
"type": "integer",
"minimum": 0
}
},
"required": ["firstName", "lastName"]
}
Save this file somewhere in your project and refer to it instead of /path/to/yourschema.json.
