Share a small program that counts the amount of code

This article mainly shares the relevant information about a small program that counts the amount of code and has some reference value. if you are interested, you can refer to it and run it directly: Select the src folder, just click "count the number of rows ".

The above is the details of a small program that collects statistics on the amount of code. For more information, see other related articles in the first PHP community!
