php - Google App Engine dns_get_record -

i getting fatal error "call undefined function dns_get_record" in live environment when making dns_get_record request works fine in google app engine sdk environment.

why?

google app engine lists details of php runtime environment here: https://cloud.google.com/appengine/docs/php/

dns_get_records built in function in versions of php since 5.0 performing dns lookups in code.

unfortunately google has not documented php src compiling against appears disable dns_get_record function.

you out of luck.
