;-)
In PHP 5 it could be done in a "non-cheating way" with iterators for
example. The RecursiveDirectoryIterator, maybe in conjunction with a
RecursiveIteratorIterator (sic!), can be very helpful:
function findDirsWithJpegs($path) {
$result = array();
$di = new RecursiveDirectoryIterator($path);
foreach (new RecursiveIteratorIterator($di) as $item) {
if ($item->isFile() && preg_match('#\.jpe?g$#i', $item->getFilename())) {
$result[] = $item->getPath();
}
}
return $result;
}
