directory scan

[unfocusedorg]

Right now I have a code snippet that opens a given directory and finds the three most recently modified files in that directory. IS there any way to modifiy it so that it checks all of the SUBDIRECTORIES of the original directory for the three most recently modified images?

chdir ($dir);
$handle = opendir(".");
$c = 0;
$date = array();
$files = array();
while ($file = readdir ($handle))
{
if ($file != "." && $file != ".." && $file != "index.php" && $file != "index2.php")
{
$date[$c] = filemtime ($file);
$files[$date[$c]] = $file;
$c++;
}
}
rewinddir ($handle);
closedir ($handle);
rsort ($date);

basically you use recursion, I couldn't be bothered to work out how you would do exactly what u want to do but you can get the picture with the code below. You call the function from within the function.

function dir($dir)
{
$dh = opendir($dir);
while($file = readdir($dh))
{
if(is_dir("$dir$file"))
{
dir("$dir$file");
}
else
{
// do whatever
}
}
closedir($dh);
}
