Usage

Json String

$jsonString = '{"$schema":"http://json-schema.org/draft/2020-12/schema","$id":...'; 

$schema = new JsonSchemaImpl($jsonString);
$jsonSchemaMerger = new JsonSchemaMergerImpl($schema, new JsonSchemaFactory());
$mergedSchema = $jsonSchemaMerger->getMergedSchema();

var_dump($mergedSchema->getSchemaString());
var_dump($mergedSchema->getSchemaArray());
var_dump($mergedSchema->getSchemaObject());

Json File

$fh = new FileHandlerImpl('/my/json/file.json');

$schema = new JsonSchemaImpl($fh->getContent());
$jsonSchemaMerger = new JsonSchemaMergerImpl($schema, new JsonSchemaFactory());
$mergedSchema = $jsonSchemaMerger->getMergedSchema();

var_dump($mergedSchema->getSchemaString());
var_dump($mergedSchema->getSchemaArray());
var_dump($mergedSchema->getSchemaObject());

Explanation

Internal Subschema Referenc

Example Json-Schema before Reference Merging:

{
  "$schema": "http://json-schema.org/draft/2020-12/schema",
  "$id": "ns://davidschmucker/jsonschemamerger/Testfiles/testStartFile",
  "title": "Start File Test Schema",
  "description": "Json Schema for Testing JsonSchema Merger",

  "type": "object",
  "properties": {
    "internalSubSchemaRef": {"$ref": "#/$defs/internalSubSchemaRefExample"}
  },

  "$defs": {
    "internalSubSchemaRefExample": {
      "type": "object",
      "properties": {
        "subreference": {"$ref": "#/$defs/subreferenceExample"}
      }
    },
    "subreferenceExample": {
      "type": "string"
    }
  }
}
