The mapping for local enum, local sequence, local dictionary and local struct to PHP is identical to the mapping for these constructs without the local qualifier. The generated PHP code for local enums and structs does not include support for marshaling, so you cannot use them as parameters for operations on non-local types, or as data members on non-local types.
Data members on local Slice types (classes, exceptions and structs) are mapped to PHP just like the data members of the corresponding non-local Slice construct.
The rest of this section describes the mapping of the remaining local types to PHP:
