title: file type post return file size is zero in laravel 5
body: <p>this is the scenario
  I'm uploading 858 KB file
  but in Controller it is 0kb 
  and when I'm saving in storage_path()  it was empty  </p>
  
  <p>I'm saving the Image on /storage  and it was corrupted 
  How can I fix this</p>
  
  <pre><code>   //this is the controller
  
     $input = $request-&gt;all();
     echo  $request-&gt;file('image_path')-&gt;getClientSize();
     dd($input);
  </code></pre>
