Do you know any tool which can count all the code lines from a PHP project?
On a POSIX operating system (e.g. Linux or OS X) you can write the following into your Bash shell:
wc -l `find . -iname "*.php"`
This will count the lines in all php-files in the current directory and also subdirectories. (Note that those single 'quotes' are backticks, not actual single quotes)
