title: How to find and replace a string in all files of a project using netBeans
body: <p>I have a PHP project in NetBeans</p>
  
  <p>I have a constant named <code>KEY</code> and I want to change it to <code>SECURE</code> . This constant is spread through out many files of my project. How can I approach this very quickly. I've heard of refactoring, and even tried it but it only renamed the current file and not the whole project's files.</p>
