title: Twilio PHP API Librarie: Warning: file_get_contents(): SSL operation failed with code 1
body: <p>I installed Official Twilio PHP API Librarie via composer ( "twilio/sdk": "~3.12" ).</p>
  
  <p>When I trying use API ( for example send an SMS ) using Test Credentials I get the error:</p>
  
  <blockquote>
    <p>Warning: file_get_contents(): SSL operation failed with code 1.
    OpenSSL Error messages: error:14090086:SSL
    routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed in
    ..vendor/twilio/sdk/Services/Twilio/HttpStream.php line 62</p>
  </blockquote>
  
  <p>If I trying send SMS in terminal using curl - everything is OK.</p>
  
  <p>How it may be fixed without editing Twilio PHP API Librarie code?</p>
