[mapserver-users] getShape failing; changes from mapserver 5.6 to 6.0

[Lime, Steve D (DNR)]

Yup, sorry it's Perl. The getResult($) should be getResult($i). Syntax for PHP should be pretty close I think, method names are the same.

Thanks a lot, Steve.

However, I had tried this out before, but "getResult($)"? I think this is Perl, no? In PHP this would be different?

Sorry for a dumb question…
