logmanoriginal f3d3582af1 Change all nested functions to member functions
This fixes error "Using $this when not in object context"

Nested functions are not part of the object and therefore don't have
access to the object instance $this!

This also fixes an error where calling collectData multiple times would
result in an attempt to redeclare all nested functions (which would
cause errors)
