要获取远程主机上目录的大小,可以使用PHP的FTP扩展或者SSH2扩展。以下是两种方法的示例代码:
$ftp_server = "ftp.example.com";
$ftp_username = "your_username";
$ftp_password = "your_password";
$conn_id = ftp_connect($ftp_server) or die("Could not connect to $ftp_server");
if (@ftp_login($conn_id, $ftp_username, $ftp_password)) {
echo "Connected to $ftp_server\n";
$size = ftp_size($conn_id, "/path/to/directory");
echo "Directory size: $size bytes\n";
} else {
echo "Login failed\n";
}
ftp_close($conn_id);
$host = "ssh.example.com";
$username = "your_username";
$password = "your_password";
$connection = ssh2_connect($host);
ssh2_auth_password($connection, $username, $password);
$stream = ssh2_exec($connection, "du -s /path/to/directory");
$output = stream_get_contents($stream);
list($size, $directory) = explode("\t", trim($output));
echo "Directory size: $size bytes\n";
这两种方法都可以获取远程主机上目录的大小。使用哪种方法取决于远程主机是否支持FTP或SSH。请注意,这些示例代码仅供参考,实际使用时可能需要根据具体情况进行修改。
