title: Please set a valid PHP executable for this launch
body: <p>I have just started Eclipse for developing PHP.  I did the first project in the book and it went great with a bit of help from you all.</p>
  
  <p>Then I opened a second project.  While trying to configure the run path (Eclipse always starts out pointing to my server's root), Somehow I got the IDE in a state that I can't get it out of.  It pops up a dialog box when I try to run the project with the title <strong>"launch error"</strong> and in the box it says: <strong>"Please set a valid PHP executable for this launch"</strong>.  I think it has something to do with the debugger which I am not using yet.  My code is very simple, in file one:</p>
  
  <pre><code>&lt;?php 
     include('helloObj.php');
     $hello= new hello();
  
     $hello-&gt;prntMessage();
  ?&gt;
  </code></pre>
  
  <p>And in file two:</p>
  
  <pre><code>&lt;?php 
  
  class Hello {
      var $message;
  
      function __construct() {
          $this-&gt;message= "Hello World!";
      }
  
      /**
        * Function that prints the value of the instance variable 
        * $message
        */
      function prntMessage() {
          echo $this-&gt;message;
      }
  }
  
  ?&gt;
  </code></pre>
  
  <p>This was copied off a tutorial on the web (and works just fine in my browser) so I don't think it is the cause.  </p>
  
  <p>Also, if someone could tell me the recommended way to configure PHP run paths in Eclipse, I would appreciate that too.</p>
