I have the following PHP script, test.php in my Moodle plugin:

    <?php
    include('lib/httpful/httpful.phar');
   
        try{
            $response = \Httpful\Request::post($uri)                
                ->body($requestbody)            
                ->send();       
        }catch (Exception $e) {
            echo "Exception occurred";
        }
    ?>
Whenever an exception occurs the text "Exception Occurred" is displayed as expected.
Then I moved the code to a function in a class classes\http_client.php. Thus:

    class http_client{
      public function doPost($uri, $requestbody){
      
        try{
            $response = \Httpful\Request::post($uri)                
                ->body($requestbody)            
                ->send();       
        }catch (Exception $e) {
            echo "Exception occurred";
        }
      }
    }
Now I try to invoke from test.php:

    $client = new http_client();
    $client->doPost($uri, $requestbody);
The exceptions are no longer caught and the stack trace is displayed in the browser.

I have to mention that it only happens within Moodle. Outside Moodle the class http_client works fine, the catch block is executed.

My settings are: Moodle 3.0.1+ (Build: 20151223), PHP 5.5.12, Apache 2.4.9.

Thanks in advance
