Dem Ziel-Verzeichnis, das Sie wollen, um die Dateien zu verschieben sollte beschreibbar durch den webserver Benutzer. Vergessen Sie auch nicht, dass manche Webserver betrieben innerhalb einer changeroot, so dass ein Teil des Ziel-Pfad kann möglicherweise nicht erforderlich sein. Die PHP-Hilfe doc auch sagt, dass Sie sollten überprüfen, die HTLM-Formular, um sicherzustellen, dass es enctype='multipart/form-data'.

Und schließlich: wo wird $filename definiert?
