issue #6831 Failure to recognize class array with PHP in @var

There are 2 different situations here:
- @var, here a special change is necessary to check and handle  whether or not we are in PHP (declinfo.*, doxygen.cpp)
- @param
  - the type recognition for the PHP type has to be extended with the `[]` possibility and subsequently the `[]` part has to be handled separately from the 'datatype' (doctokinizer.l, docparser.*).
  - In the output we now can have multiple text strings resulting in a small change in handling of the separator between the data type (*docvisitor.*)
