Mostly used find-and-replace: Find: /\*[\*\s]+@var (I?[A-Z](\w+)(?:Interface)?)[\s\*]+/\s*(private|protected|public) (\$[a-z]\w+;\n)((?=\s*/\*[\*\s]+@var (I?[A-Z](\w+)(?:Interface)?))\n|) Replace with: \3 \1 \4 Followed by some manual review to make sure I'm not changing too much, omitting some changes that looked too complicated and anything that caused test failures, and some whitespace fixes.
