ftp_cdup

Example 356. Move to child directory then back to parent

// Define directory to which to change
$subdir = "oneleveldown";

// Turn on $php_errormsg (PHP 4.0RC1 and up)
ini_set('track_errors', true);

// Connect to server, or complain to user and die
$ftpStream = @ ftp_connect("my.ftp.server")
   or die("Couldn't connect to FTP server.");

// Log in to server, or complain to user and die
$loginResult = @ ftp_login($ftpStream, "username", "password")
   or die("Couldn't log in to FTP server: $php_errormsg");

// Change to directory named 'oneleveldown' 
@ ftp_chdir($ftpStream, $subdir)
   or die("Couldn't change to directory '$subdir': $php_errormsg");

print "Directory before ftp_cdup(): " . @ ftp_pwd($ftpStream) . "<br>\n";

@ ftp_cdup($ftpStream)
   or die("Couldn't change to parent directory: $php_errormsg");

print "Directory after ftp_cdup(): " . @ ftp_pwd($ftpStream) . "<br>\n";
