rewrite regex limitation

We encountered issue with rewrite regex on Nginx - basically we have bellow rule, which would rewrite URL like http://www.domain.com/php/api_name/xxx=1/yyy=2/zzz=3....
to hit specific PHP script and would populate $_GET with list of sent parameters. For some reason any parameters after 9th will be not set in $_GET. It adds api0, api1, api2.... unset parameters.

Any idea if there is a way to reset some default limit or solution of such rewrite would be appreciated.

Thanks
