Introduction to json schema below (and tools) :

-  — reference
-  - validator (not 100% valid)
-  - use json schema to define REST API docs
-  - convenient editor for json schema

To validate your structure against a given schema, you can use :

-

Quickstart
----------

[](#quickstart)

Install using composer

```
composer require evaisse/php-json-schema-generator

```

Most simple case

```
$output = JSONSchemaGenerator\Generator::fromJson('{"a":{"b":2}');

// $output ==> json string
// {
//   "$schema": "http://json-schema.org/draft-04/schema#",
//   "type": "object",
//   "properties": {
//     "a": {
//       "type": "object",
//       "properties": {
//         "b": {
//           "type": "integer"
//         }
//       },
//       "required": ["b"]
//     }
//   },
//   "required": ["a"]
// }

```

Default configuration values

```
[
    'schema_id'                      => null,
    'properties_required_by_default' => true,
    'schema_uri'                     => 'http://json-schema.org/draft-04/schema#',
    'schema_title'                   => null,
    'schema_description'             => null,
    'schema_type'                    => null,
    "items_schema_collect_mode"      => 0,
    'schema_required_field_names'    => []
]

```

Advanced usage

```
$result = Generator::fromJson($this->addressJson1, [
    'schema_id' => 'http://foo.bar/schema'
]);

/*

  {
    "$schema": "http://json-schema.org/draft-04/schema#",
    "id": "http://foo.bar/schema",
    "type": "object",
    "properties": {
      "a": {
        "type": "object",
        "id": "http://foo.bar/schema/a",
        "properties": {
          "b": {
            "id": "http://foo.bar/schema/a/b",
            "type": "integer"
          }
        }
      }
    }

*/

// if you want items as strict lists instead of "anyOf" type
$result = Generator::fromJson($this->addressJson1, [
    'schema_id'                      => 'http://bar.foo/schema2',
    'schema_title'                   => 'coucouc',
    'schema_description'             => 'desc',
    "items_schema_collect_mode"      => Definition::ITEMS_AS_LIST,
]);

/*
    {
        "$schema":"http:\/\/json-schema.org\/draft-04\/schema#",
        ...
        "properties": {
            "phoneNumber":{
                "id":"http:\/\/bar.foo\/schema2\/phoneNumber",
                "type":"array",
                "items": [
                    {"id":"http:\/\/bar.foo\/schema2\/0",...},
                    {"id":"http:\/\/bar.foo\/schema2\/1",...}}
*/

```

Testing
-------

[](#testing)

just run phpunit through

```
composer test

```

debug with

```
DEBUG=true composer test -- --filter="SearchWord" # for filtering *SearchWord* test case with output debugging

```

Roadmap
-------

[](#roadmap)

- Adjust schema comparison using re-ordering of properties to compare two schema against their semantic values instead of just comparing their JSON form. For example `{ a: 1, b: 2 }`, and `{ b: 2, a: 1 }`should result in the same schema.
- provide an option to allow null values in most fields `("type": ["string", "null"]}`
