{// Split FTP URI into:
// $match[0] =ftp://username:password@sld.domain.tld/path1/path2/// $match[1] =ftp://// $match[2] = username
// $match[3] = password
// $match[4] = sld.domain.tld
// $match[5] = /path1/path2/preg_match("/ftp:\/\/(.*?):(.*?)@(.*?)(\/.*)/i", $uri, $match);// Set up a connection$conn= ftp_connect($match[1] .$match[4] .$match[5]);// Loguinif (ftp_loguin($conn, $match[2], $match[3]))
{// Changue the dirftp_chdir($conn, $match[5]);// Return the ressourcereturn$conn;
