GetCampaigns.php doesn't return results

[Marcos Gil Fuertes]

Just downloaded the PHP library, configured everything at "google_ads_php.ini" file and tested the sample... but it doesn't show any campaign (and I have a couple of them on my test account).

This is the trace:

I can't understand very well the response header "content-disposition": "attachment" :/

Did I miss something?

Thank you!
