Example #1 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);
}
