Warning: ftp_get(): Opening data channel for file transfer. in /usr/home/public_html/admin/cron/tassn.php on line 30
fail
download 'rus_hot_613740.xml' to '/usr/home/public_html/files/_xml/out/rus_hot_613740.xml'...PHP Warning: ftp_get(): Transfer OK in /usr/home/public_html/admin/cron/tassn.php on line 30

Warning: ftp_get(): Transfer OK in /usr/home/public_html/admin/cron/tassn.php on line 30
