As stated here https://bugs.php.net/bug.php?id=55701 the count() method can lead to errors.

For example this won't works if no files are found in the target directory :

<?php
$iterator = new \GlobIterator($ftpDirectory . '/*.*', FilesystemIterator::KEY_AS_FILENAME);

if($iterator->count()) {
    foreach($iterator as $filePath) {
        // do some stuff ...
    }
}
?>

A workaround to this bug could be :

<?php
foreach(new \GlobIterator($ftpDirectory . '/*.*', FilesystemIterator::KEY_AS_FILENAME) as $filePath) {
    // do some stuff ...
}
?>
