What are some best practices for handling FTP directory and file checks in PHP?

When working with FTP directories and files in PHP, it is important to handle checks for their existence before performing any operations on them. This can help prevent errors and ensure that the script runs smoothly. One best practice is to use functions like `ftp_nlist()` to get a list of files in a directory and then check if the desired file or directory exists in that list. 

// Connect to FTP server
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$ftp_conn = ftp_connect($ftp_server);
ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Check if directory exists
$directory = '/path/to/directory';
$files = ftp_nlist($ftp_conn, $directory);
if (in_array('file.txt', $files)) {
    echo 'File exists in directory';
} else {
    echo 'File does not exist in directory';
}

// Close FTP connection
ftp_close($ftp_conn);
