title: PHP get browser: confusing output
body: <p>I have a list containing information on the user's web browser. The list was generated by PHP through a user requirements survey. The output looks like this: (sample): </p>
  
  <ul>
  <li>Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)</li>

  </ul>
  
  <p>Which is the actual web browser? According to the PHP manual, it would be 
  [parent], [platform], [browser], [version], but why does it say Safari and Chrome in one row, and why does "MSIE" appear inside the brackets?</p>
