Let's see if it works. There is a utility on the Start Page of Komodo for doing this, however we will also look at the php.ini file that the wizard created and add a few more parameters to get it all working.

To start with, we can use the Check Configuration feature on the Komodo Start Page:

Click on the Check Configuration link and if all is well you should see something like the following:

Now we should look at the php.ini file created by the wizard. So load it up in your favourite editor.

Here we can see what the wizard added. I found in my version of Komodo that the remote_host and ide_key values were not defined so I added them. My configuration did not seem to work without them. You may find similar problems and may need to change your remote_host to 127.0.0.1

One final test would be to do a phpinfo test in your web browser and ensure you can see Xdebug defined in the resulting page. If you cannot then php is not configured correctly. From the command line a php -m will show the compiled modules, and if your path is picking up the correct php then you should see Xdebug listed under a [Zend Modules] section of the output.

Ok, now the moment of truth, let's try to debug something...
