What are the limitations of using HTTP for accessing file information on remote servers in PHP?

When using HTTP to access file information on remote servers in PHP, there are limitations such as slower performance due to network latency and potential security risks if the server is not properly configured. To overcome these limitations, it is recommended to use more secure and efficient protocols like FTP or SSH for accessing remote files. 

// Example of accessing file information on a remote server using FTP
$ftp_server = 'ftp.example.com';
$ftp_user = 'username';
$ftp_pass = 'password';
$remote_file = '/path/to/file.txt';

// Connect to FTP server
$conn_id = ftp_connect($ftp_server);
$login_result = ftp_login($conn_id, $ftp_user, $ftp_pass);

// Get file information
$file_size = ftp_size($conn_id, $remote_file);
$file_modified = ftp_mdtm($conn_id, $remote_file);

// Close FTP connection
ftp_close($conn_id);

// Output file information
echo "File size: $file_size bytes\n";
echo "Last modified: " . date('Y-m-d H:i:s', $file_modified) . "\n";
