Support us

We invest a lot of resources into creating best in class open source packages. You can support us by buying one of our paid products.

We highly appreciate you sending us a postcard from your hometown, mentioning which of our package(s) you are using. You'll find our address on our contact page. We publish all received postcards on our virtual postcard wall.

Usage

Create a Client

use Zymawy\Dgraph\DgraphClient;

/** @var DgraphClient $client */
$client = new DgraphClient('https://localhost:8080');

Define and Alter Schema

use Zymawy\Dgraph\Api\Operation;
use Zymawy\Dgraph\Exceptions\DgraphException;
use Zymawy\Dgraph\Types\StringType;
use Zymawy\Dgraph\Types\IntType;
use Zymawy\Dgraph\DgraphClient;

/** @var DgraphClient $client */
$client = new DgraphClient('https://localhost:8080');

// Define the schema using the Operation class
$operation = new Operation();
$operation
  ->addField("name", new StringType(["index(term)"]))
  ->addField("age", new IntType(["index(int)"]))
  ->addType("person", ["name", "age"]);

try {
    $response = $client->alter($operation);
    if ($response->hasErrors()) {
        throw new DgraphException("Schema alteration error: " . json_encode($response->getErrors()));
    } else {
        echo "Schema successfully altered.";
    }
} catch (DgraphException $e) {
    echo "Error: " . $e->getMessage();
}

Add Initial Data

use Zymawy\Dgraph\DgraphClient;
use Zymawy\Dgraph\Txn;
use Zymawy\Dgraph\Responses\DgraphResponse;
use Zymawy\Dgraph\Exceptions\DgraphException;
use Zymawy\Dgraph\Types\StringType;
use Zymawy\Dgraph\Types\IntType;
/** @var DgraphClient $client */
$client = new DgraphClient("https://localhost:8080");

use Zymawy\Dgraph\Api\Mutation;
use Zymawy\Dgraph\Exceptions\DgraphException;

/** @var DgraphClient $client */
$client = new DgraphClient("https://localhost:8080");

$mutation = new Mutation();
$mutation->set([
  [
    "uid" => "_:account1",
    "name" => "Hamza",
    "balance" => 1000.0
  ],
  [
    "uid" => "_:account2",
    "name" => "Zymawy",
    "balance" => 500.0
  ]
]);

try {
  $response = $client->mutate($mutation, true); // commitNow set to true
  if ($response->hasErrors()) {
    throw new DgraphException(
      "Mutation error: " . json_encode($response->getErrors())
    );
  } else {
    print_r($response->getData());
  }
} catch (DgraphException $e) {
  echo "Error: " . $e->getMessage();
}
