Description:
------------
im used php 5.2.9

after running some tests, it keeps telling me a txt file IS A DIRECTORy.. then fails to open it


if this is human error, im sorry and could you point me in the right direction?




Reproduce code:
---------------
function a($hutpear) {
	$abc = $hutpear;
	if ($handle = opendir($abc)) {
		while (false !== ($file = readdir($handle))) {
			if ($file != "." && $file != "..") {
				if  (!is_file($file)) {
					a($abc . "/" . $file);
				} else {
					echo "$file\n";
				}
			}
		}
		closedir($handle);
	}
}

a("photos");

Expected result:
----------------
thisisafile.txt

Actual result:
--------------
br />
<b>Warning</b>:  opendir(photos/1/thisisatextdocument.txt) [<a href='function.opendir'>function.opendir</a>]: failed to open dir: Not a directory in <b>/home/y02wals/public_html/test.php</b> on line <b>6</b><br />
