How to measure # of lines of code in project?

Check CLOC, it's a source code line counter that supports many languages, I always recommend it.

It will differentiate between actual lines of code, blank lines or comments, it's very good.

In addition there are more code counters that you can check:

• SLOCCount
• sclc
• USC's CODECOUNT
• loc
• Ohcount

phploc

No experience if it runs on Windows, tho, but searching on the web showed some results of people getting it to work on Windows..
