PHP连接sftp并下载文件的方法教程

sftp -P port user@host

sftp user@host

$conf = [
 'channelId' => '',
 'host' => '',
 'port' => '',
 'user' => '',
 'password' => ''
];
$conn = ssh2_connect($conf['host'], $conf['port']);

if (!ssh2_auth_password($conn, $conf['user'], $conf['password'])) {
 var_dump('ftps 连接失败');
}

$remotFile = '/file/xxx/xxx/xxx.txt';

$localPath = '/storage/data';

// 创建文件夹
if (!is_dir($localPath)) {
 $dir = mkdir($localPath, 0777, true);
 if (!$dir) {
  return false;
 }
}

// 如果文件已存在就覆盖
$localFile = 'xxxxx.txt';

$localRealFile = $localPath . '/' . $localFile;

// 如果文件存在则删除，当然这里也可以根据需求进行修改
if (is_file($localRealFile)) {
 unlink($localRealFile);
}

$sftp = ssh2_sftp($conn);

$resource = "ssh2.sftp://{$sftp}" . $remotFile;

//远程文件 拷贝到本地
copy($resource, $localRealFile);
