如何计算PHP项目中的代码行？

Question

I'd like to count the the lines of code of a PHP-project in a given git repository. Currently I'm using:

git ls-files -- *.php* | xargs wc -l

to count the lines of code in all php files.

It would be great to have a step before counting all lines, that skips all empty lines and maybe also lines containing comments (in PHP this in # and // for single line comments and /* */ for multiline comments). I guess sed might help, but how to handle multiline comments?

Answer 1

You may use powershell for this as pointed out here. Open Powershell and go to the directory with your PHP-files. Issue the following command:

(dir -include *.php -recurse | select-string .).Count

If you want files of other file types to be included, simply add them like

(dir -include *.php, *.js -recurse | select-string .).Count

If there aren't any subdirectories, the command would be

(dir *.php | select-string .).Count
