For detecting folders use function ::getNameIndex:
//$zip = ZipArchive::open()
$entry = $zip->getNameIndex($i);
$isDir = (substr($entry, -1, 1) == '/');

both getFromIndex and getFromName leak memory. Beware specially if you use them inside a long running loop. Even closing and re-opening the zip file doesn't help.

Unlike what "jana.vasseru" said 7 years ago, this method does not return FALSE for folders (anymore?). It seems that there is no way to find out if an entry is a directory of file.

Note, length is in characters and not bytes.

Note that getFromIndex returns false for directories.
