How can FTP be integrated into PHP scripts to circumvent access restrictions on files?

To circumvent access restrictions on files, FTP can be integrated into PHP scripts to allow for file transfers between servers. By using FTP functions in PHP, you can access and manipulate files that may otherwise be restricted due to permissions. This can be useful for tasks such as downloading files from a remote server or uploading files to a different location.

// Connect to FTP server
$ftp_server = "ftp.example.com";
$ftp_username = "username";
$ftp_password = "password";
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_username, $ftp_password);

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

// Close FTP connection
ftp_close($conn_id);
