title: How to select files that begin with a certain word in PHP?
body: <p>I have a small php app that needs to read multiple xml data files. The files will be generated in the following fashion:</p>
  
  <pre><code>contractors1.xml
  contractors2.xml
  contractors3.xml
  ...
  contractors100.xml
  </code></pre>
  
  <p>How do I select any file in the directory that begins with "contractors" followed by a number that ends with ".xml"?</p>
