From the error, it seems you are using your GCS Object Link for gsutil in your PhP function, instead of using the GCS Object's Link URL. This documentation on the section "A user granted access to an object" explains in detail how to access your contents via the Link URL. The GCS Object Link for gsutil should be used within a gsutil environment. I believe it worked for your App Engine application because GAE can still be considered to be within the gsutil environment.
