PHP : Function Reference : FTP Functions : ftp_systype

ftp_systype

Returns the system type identifier of the remote FTP server (PHP 4, PHP 5)
string ftp_systype ( resource ftp_stream )

Example 751. ftp_systype() example

<?php

// ftp connection
$ftp = ftp_connect('ftp.example.com');
ftp_login($ftp, 'user', 'password');

// get the system type
if ($type = ftp_systype($ftp)) {
   echo
"Example.com is powered by $type\n";
} else {
   echo
"Couldn't get the systype";
}

?>

The above example will output something similar to:

Example.com is powered by UNIX

ftp_systype can be a good way of checking the state of a connection, since PHP doesn't have a better system to check the state of an ftp connection (is_connected would be nice).
if (!($type = ftp_systype($conn_id))) {
   echo "FTP connection has failed! Trying again.\n";
   $conn_id = ftp_connect($ftp_server);
   $login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);
}
