What alternative solutions or technologies, such as SSHFS, can be considered for accessing and manipulating files on remote volumes in PHP applications?

One alternative solution to accessing and manipulating files on remote volumes in PHP applications is using FTP (File Transfer Protocol) to connect to the remote server and perform file operations. Another option is to use cURL (Client URL Library) to make HTTP requests to the remote server and handle file operations through the HTTP protocol. Additionally, cloud storage APIs such as Amazon S3 or Google Cloud Storage can be integrated into PHP applications for accessing and manipulating files stored remotely.

// Example using FTP to access and manipulate files on a remote server
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';

// Connect to FTP server
$ftp_conn = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");

// Login to FTP server
$login = ftp_login($ftp_conn, $ftp_user, $ftp_pass);

// Change directory
ftp_chdir($ftp_conn, '/path/to/remote/directory');

// List files in directory
$files = ftp_nlist($ftp_conn, '.');

// Download file
ftp_get($ftp_conn, 'local_file.txt', 'remote_file.txt', FTP_BINARY);

// Upload file
ftp_put($ftp_conn, 'remote_file.txt', 'local_file.txt', FTP_BINARY);

// Close FTP connection
ftp_close($ftp_conn);
