How can FTP functions in PHP be utilized to overcome safe_mode restrictions when accessing files on a web server?

To overcome safe_mode restrictions when accessing files on a web server, you can utilize FTP functions in PHP to interact with files outside of the web server's directory. By connecting to an FTP server, you can read, write, and manipulate files without being limited by safe_mode restrictions. 

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

// Download file from FTP server
$local_file = 'local_file.txt';
$remote_file = 'remote_file.txt';
if (ftp_get($conn_id, $local_file, $remote_file, FTP_ASCII)) {
    echo "Successfully downloaded $remote_file\n";
} else {
    echo "Error downloading $remote_file\n";
}

// Upload file to FTP server
$local_file = 'local_file.txt';
$remote_file = 'remote_file.txt';
if (ftp_put($conn_id, $remote_file, $local_file, FTP_ASCII)) {
    echo "Successfully uploaded $local_file\n";
} else {
    echo "Error uploading $local_file\n";
}

// Close FTP connection
ftp_close($conn_id);
