You can create a Message object from the string, followed by extracting the info you'd need from each segment. For example,

public function toJson(string $hl7): string
{
  return json_encode($this->toArray($hl7));
}

public function toArray(): array
{
    $msg = new Message($hl7String, null, true, true, true, true);
    $pv1 = $msg->getFirstSegmentInstance('PV1');
    $data['physician'] = $pv1->getOrderingProvider(); // This may need to be further parsed for lastname, firstname, NPI etc. Recommended to be in its own function as the logic may get complex
    // Likewise, $data['patient'] = $pid->getPatientName(), etc.
   return $data;
}

You may need to create separate classes for ORM, ORU, OML depending upon the type of messages you're dealing with.
