Classes, interfaces and traits
PVCommunicator¶
PVCommunicator opens up communication with other services via Curl, SOAP, or Sockets.
With the rise of RESTFUL API and Microservices, this class was designed to allow easy communication with those services without having to rewrite the underlying commands.
Example:
```php
//CURL GET
$url = 'http://api.wunderground.com/api/Your_Key/conditions/q/CA/San_Francisco.json';
$communicator = new PVCommunicator();
$communicator->send('get', $url);
print_r($communicator ->getResponseBody());
//CURL POST
$url = 'http://api.example.com/createuser';
$data = array('name' =>'John Doe', 'email' => 'johndoe@example.com')
$communicator = new PVCommunicator();
$communicator->send('POST', $url, );
print_r($communicator ->getResponseBody());
```
