[validation] How to get a php variable after an AJAX request

Hello,

I use JQuery validation plugin to handle my forms, and I'm using the remote option for some inputs, aside from the usual 'true/false' to detect if the field is valide or not, I need to get a php variable generated on the server, but I don't know how to do it, any ideas ?

Best regards,
