title: Regex for copyright line
body: <p>Hello I working with php_codesniffer for our project as we are currently trying find a way to sniff out incorrect copyrights on our source files.</p>
  
  <p>Currently I cant seem to get the result I looking for. We are trying to run preg_match for the following:</p>
  
  <pre><code>Copyright (C) 2016 - 2017 Dazzle Software, LLC. All rights reserved.
  </code></pre>
  
  <p>I tried:</p>
  
  <pre><code>^(Copyright (C))([0-9]{4})(-[0-9]{4})? (Dazzle Software, LLC.) \(All rights  reserved.\))$
  </code></pre>
  
  <p>but still not having much luck as I not experienced with regex or cant seem to find any good documentation on regex</p>
