* The matching rules are only matched from the head of the comment paragraph. If there are lines starting with // and *, # and /*, and blank lines will be Skip. Therefore, sweaty comments like /* must be preceded by an * sign, otherwise such comments cannot be matched.

The above introduces what kind of file ftnstat.stat is, the total number of files and the number of lines of code in the PHP statistics directory (removing comments and blank lines), including what kind of file ftnstat.stat is. I hope that friends who are interested in PHP tutorials can read it. helped.
