    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 ...
    }
    ?>
