Description: ------------ I have a list of directories with a series of files in each that I want to retrieve. Automatic retrieval with $ftp->getRecursive() hangs after 3 directories. For a strange reason it cannot retrieve a file (that means it is created in the destination directory but it remains with 0 size). For all the subsequent directories I get this message "Warning: Invalid argument supplied for foreach() in /usr/lib/php/FTP.php on line 1467". It retrieves then no files though it creates if needed the directories. I have tested with all the versions from 1.2, 1.3b1, 1.3b2. Reproduce code: --------------- dump($ftp->cd('/www/praktijken'), 'FTP::cd()'); $dirs = $ftp->ls(null, NET_FTP_DIRS_ONLY); for ($i=0;$i<count($dirs);$i++){ $dirnaam = $dirs[$i][name]; print $dirnaam; if (!is_dir("/www/praktijken/$dirnaam")) { umask(0); mkdir ("/www/praktijken/$dirnaam", 0755); } $ftp->getRecursive("/www/praktijken/$dirnaam/" , "/www/praktijken/$dirnaam/", true, FTP_BINARY); } Expected result: ---------------- Retrieve all files in the corresponding directories

I just tested it. It looks like it has nothing to do with the problem. It stalls at a file and after X minutes it does a timeout. The problem is the stalling. This happens in a period of 10-20 seconds (the one it takes to retrieve some 20 <1k files). Is there any way to overcome the stalling? Or any other ideas? Thanks.
