Usage

Basic usage

test.json:

{
  "Foo": {
    "Bar": "33"
  }
}

Example 1:

$jq = JsonQueryWrapper\JsonQueryFactory::createWith('test.json');
$jq->run('.Foo.Bar'); # string(33)

Example 2:

$jq = JsonQueryWrapper\JsonQueryFactory::createWith('test.json');
$jq->run('.Foo.Bar == "33"'); # Returns bool(true)

Example 3:

$jq = JsonQueryWrapper\JsonQueryFactory::createWith('{"Foo":{"Bar":"33"}}');
$jq->run('.Foo.Bar == "33"'); # Returns bool(true)

Advanced usage

Example 1:

$jq = JsonQueryWrapper\JsonQueryFactory::create();
$jq->setDataProvider(new JsonQueryWrapper\DataProvider\File('test.json');
$jq->run('.Foo.Bar == "33"'); # Returns bool(true)

Data Providers

A "Data Provider" provides the wrapper with the necessary data to read from. It's a common interface for several providers. All providers implement the DataProviderInterface which essentially returns a path to the file for jq.

Available providers:

• Text - Regular PHP string containing JSON data
• File - A path to a file containing JSON data
