title: Fopen can't open audio file
body: <p>I am trying to send an audio file to my live api from my localhost. When i send the audio file (located on my localhost) to the api, <strong>fopen</strong> is able to read the file but when i use a live url like <code>https://example.amazonaws.com/patient_file/audio.mp3</code>, Fopen fails to open it.  What could i be doing wrong below </p>
  
  <pre><code>        $audio_file = 'audio.mp3';
          $file_path = 'https://example.amazonaws.com/patient_file' . $audio_file;
          $request = $client-&gt;post($apiURL, [
                  'multipart' =&gt; [
                      [
                      'name' =&gt; 'info',
                      'contents' =&gt; 'info',
                      ],
                       [
                      'name' =&gt; 'file',
                      'contents' =&gt; fopen($file_path, 'r'),
                  ],
         $response = $request-&gt;getBody();
         return $response;
  </code></pre>
  
  <p><strong>PS</strong> allow_url_fopen is enabled</p>
