PHP + FTP delete files in folder

I just wrote a PHP Script which should connect to FTP and delete all files in a special folder.

It looks like this, but I have no clue what command I need to delete all files in the folder logs.

Any idea?

<?php

// set up the settings
$ftp_server = 'something.net';
$ftpuser = 'username';
$ftppass = 'pass';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftpuser, $ftppass);

// delete all files in the folder logs
????????

// close the connection
ftp_close($conn_id);

?>

Answer

// Delete all files in the folder logs
$logs_dir = "";
ftp_chdir($conn_id, $logs_dir);
$files = ftp_nlist($conn_id, ".");
foreach ($files as $file)
{
    ftp_delete($conn_id, $file);
}    

You might want to do some checking for directories, but at a basic level, that is it.
