请为此次启动设置有效的PHP可执行文件

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.

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 "launch error" and in the box it says: "Please set a valid PHP executable for this launch". I think it has something to do with the debugger which I am not using yet. My code is very simple, in file one:

<?php 
   include('helloObj.php');
   $hello= new hello();

   $hello->prntMessage();
?>

And in file two:

<?php 

class Hello {
    var $message;

    function __construct() {
        $this->message= "Hello World!";
    }

    /**
      * Function that prints the value of the instance variable 
      * $message
      */
    function prntMessage() {
        echo $this->message;
    }
}

?>

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.

Also, if someone could tell me the recommended way to configure PHP run paths in Eclipse, I would appreciate that too.

Do the following:

  1. Run -> Debug Configurations

  2. Chose your PHP Debugger. I chose XDebug

  3. Find your PHP executable (php.exe). In XAMPP it is at C:\xampp\php\php.exe

  4. Point to your PHP file.

  5. Press debug at bottom.

The script should run.
