PHP get create time of directory

Question

Is there anyway to find the created time of a directory in php? I've tried filectime but that only works on files.

Answer 1

In unix a folder is also a file. So it should work for that too

$folder = 'includes';

echo date ("F d Y H:i:s.", filemtime($folder));

Output is

October 06 2010 20:20:58.

Answer 2

It should work for directories, this is what I get:

$ php -r "echo filectime(__DIR__);"
