if ((!$ftp) || (!$login_result)) {
die("FTP connection has failed !");
}

`Thanks to h3 at valleyfield dot net
Same function with some minor changes and comments added
FTP function checks if a directory exists
originaldirectory=ftppwd(original_directory = ftp_pwd( originaldirectory=ftppwd(ftpcon ); // test if you can change directory to $dir // suppress errors in case $dir is not a file or not a directory if ( @ftp_chdir( ftpcon,ftpcon, ftpcon,dir ) ) { // If it is a directory, then change the directory back to the original directory ftp_chdir( ftpcon,ftpcon, ftpcon,original_directory ); return true; } else { return false; } } ?>`

`Works like the other functions in this page's notes, but this one doesn't make use of a global FTP connection, so it takes parameters like the other functions in the extension
origin=ftppwd(origin = ftp_pwd(origin=ftppwd(ftp);// Attempt to change directory, suppress errors if (@ftp_chdir($ftp, $dir)) { // If the directory exists, set back to origin ftp_chdir($ftp, $origin); return true; }// Directory does not exist return false; } ?>[NOTE BY danbrown AT php DOT net: As the contributor mentions, the original function was noted here by (h3 AT valleyfield DOT net) on 13-JUL-2007.]
