These numbers are from chunked encoding incorrectly sent by apache
to nginx. This behaviour is the result of a bug in apache's
mod_php which forces HTTP/1.1 reply despite the fact client
(nginx) uses HTTP/1.0 in request.

To fix this, just change

header('HTTP/1.1 ...');

to

header('HTTP/1.0 ...');

in your php code, or use "SetEnv downgrade-1.0" in apache config
as a workaround if changing code is problematic for some reason.
