What does “ *RECURSION* ” in print_r output mean?

Question

I\'m using this recursive code to read all directories inside another directory, and store them within the parent directory.

protected function readDirs($parent)         


        

Answer 1

scandir returns the . entry, which represents the current directory. You then go to store this directory inside its parent (itself). Thus, recursion.

I suggest ignoring . and ...

The "RECURSION" message you got means the data structure cannot be printed in its entirety because it would be infinite.
