DirectoryIterator::isFile
There a typo in the recursive delete function, ironically with the call to isLink (incorrectly written as isSymlink).
The example function fails rather noisily if the directory to be deleted does not exist, so you might want to include a test for existence first.
DirectoryIterator::isLink

Examples
Example #1 A DirectoryIterator::isLink example
This example contains a recursive function for removing a directory tree.
<?php
/**
* This function will recursively delete all files in the given path, without
* following symlinks.
*
* @param string $path Path to the directory to remove.
*/
function removeDir($path) {
$dir = new DirectoryIterator($path);
foreach ($dir as $fileinfo) {
if ($fileinfo->isFile() || $fileinfo->isSymlink()) {
unlink($fileinfo->getPathName());
} elseif (!$fileinfo->isDot() && $fileinfo->isDir()) {
removeDir($fileinfo->getPathName());
}
}
rmdir($path);
}
removeDir('foo');
?>
