title: Inspect file in zip archive without extracting
body: <p>I wrote a short code, which opens up a Zip File and searches for a file called "index.html".
  Now I want to open the file and perform several actions.
  - Search for  links.
  - Search for clicktags.</p>
  
  <p>Please keep in mind, that this is done while the user is uploading his file.
  I dont want to extract is somewhere on the server.</p>
  
  <p>Is there a good method to achieve this?
  Regards</p>
  
  <pre><code>    $zip = new ZipArchive();
      $zip -&gt; open($filepath);
  
  
      //Assign filescount to variable
      $this -&gt;adFileCount = $zip -&gt; numFiles;
  
      //Scan all files and find index.html
      if($zip -&gt;getFromName("index.html") == true)
      {
          //specific action done with index.html
      }
  </code></pre>
