howto: debug paypal IPN. It doesnt come back via the browser

os: kubuntu 10.04
PhpStorm 2.0Beta
build: 102.18

I have debugging working for everything that i can see in the browser.  It works great.  Stops on the break points, opens included files, excellent.

The issue im having is PhpStorm is not catching and stopping for php files that are loaded behind the scenes.

When Paypal processes a transaction, it sends an IPN (Instant Payment Notification) to the website server independantly of the users browser.

So the user will go like this:
* On my site, click the "Checkout" button
* arrive at paypal -> login -> pay the money

It is at this point that Paypal sends an IPN notification back to my server.

What i was expecting to happen:
* when the paypal IPN comes in it runs a .php script.  If that script has break points in it, I expected the file to open and a stop at the break point in the same way as every other file with break points in it stops.

What actually happens:
* All break points in the IPN processing file are ignored and the script runs as if the debugger was not activated. The script does not get a tab opened in the debug console.

Anyone know any tricks to get the debugger to work in this situation?

Hello michael,

Yes, there is a special directive for xdebug which probably can help you.
Try to add the following line to your php.ini:



Type: boolean, Default value: 0
Normally you need to use a specific HTTP GET/POST variable to start remote debugging (see Remote Debugging). When this setting is set to 1, Xdebug will always attempt to start a remote debugging session and try to connect to a client, even if the GET/POST/COOKIE variable was not present.
