fixes for continue inside switch statement

[brainfoolong]

This a bugfix for php 7.3 (or even 7.2?) related errors where using continue inside a switch raises a php warning. Either use continue 2 or break. Previously continue behaves like break but the intended usage is to continue the for loop instead, i guess.

I cannot find anything related to that in http://php.net/manual/en/control-structures.switch.php. Do you another reference ?

Yep, 7.3 change -> see https://github.com/php/php-src/blob/php-7.3.0RC2/UPGRADING Point 1 -> Backward Incompatible Changes ->

"continue" statements targeting "switch" control flow structures will now
generate a warning. In PHP such "continue" statements are equivalent to
"break", while they behave as "continue 2" in other languages.

Thanks for the PR !

Are you sure that it is a proper fix?
When I look at _readPpsWks
It seems like, if first $type go to default - there will be error (since $pps wouldn't be defined).
If it is not first iteration, that goes to default - previous $pps will be modified.
