如何计算PHP目录中的.txt文件数？

Question

I'm working on an IMDB style website and I need to dynamically find the amount of reviews for a movie. The reviews are stored in a folder called /moviefiles/moviename/review[*].txt where the [*] is the number that the review is. Basically I need to return as an integer how many of those files exist in that directory. How do I do this?

Thanks.

Answer 1

Take a look at the glob() function: http://php.net/manual/de/function.glob.php
You can then use sizeof() to count how many files there are.
