FTP: Getting a Directory Listing
| We'll start our FTP work by using the ftp_nlist function to get a listing of a remote directory; here's how you use this function: array ftp_nlist(resource ftp_stream, string directory) This function returns an array of filenames from the specified directory on success or FALSE on error. In this case, we'll connect to an FTP server and get a listing of the directory code22 on that server. Here's how we connect to the FTP server: <?php $connect = ftp_connect("ftp.ispname.com"); $result = ftp_login($connect, "username", "password"); . . . ?> We get the listing of the files in the code22 directory this way: <?php $connect = ftp_connect("ftp.ispname.com"); $result = ftp_login($connect, "username", "password"); $a = ftp_nlist($connect, "code22"); . . . ?> And we'll display the files in that directory this way: <?php $connect = ftp_connect("ftp.ispname.com"); $result = ftp_login($connect, "username", "password"); $a = ftp_nlist($connect, "code22"); foreach($a as $value){ echo $value, "<BR>"; } ?> All this is put to work in phpftp.php, Example 9-4.
