title: PHP form does not generate tmp_name - multiple upload
body: <p>I am trying to proccess multiple upload of images via php. Problem is, that array contains no <code>tmp_name</code> parametr for each file so after upload I cant work with images. I have tried it on two different servers with the same behavior.</p>
  
  <p>Images are upload via this input: </p>
  
  <pre><code>&lt;input multiple="multiple" id="file_archive[]" name="file_archive[]" size="60" type="file" /&gt;
  </code></pre>
  
  <p>generated $_FILES array (without specific tmp_name for each file):</p>
  
  <pre><code> array(1) {
    ["file_archive"]=&gt;;
    array(5) {
      ["name"]=&gt;;
      array(2) {
        [0]=&gt;;
        string(14) "logo_white.png"
        [1]=&gt;;
        string(8) "logo.png"
      }
      ["type"]=&gt;;
      array(2) {
        [0]=&gt;;
        string(9) "image/png"
        [1]=&gt;;
        string(9) "image/png"
      }
      ["tmp_name"]=&gt;;
      string(38) "/opt/lampp/htdocs/cms/back/inside/tmp/"
      ["error"]=&gt;;
      array(2) {
        [0]=&gt;;
        int(0)
        [1]=&gt;;
        int(0)
      }
      ["size"]=&gt;;
      array(2) {
        [0]=&gt;;
        int(24115)
        [1]=&gt;;
        int(38663)
      }
    }
  }
  </code></pre>
  
  <p>Form is set as <code>enctype="multipart/form-data"</code></p>
  
  <p>Script generates no errors.</p>
  
  <p>Thank you for any reply.</p>
