[Laravel 实现 SFTP 读取数据库数据上传 CSV 文件 | Laravel China 社区 - 高品质的 Laravel 和 PHP 开发者社区]

控制器：

 public function getSftpData(){
    ini_set('max_execution_time','0');//设置永不超时
    $time = date('Ymd',time());
    $name = "openid".$time;

    $data = 'id,标题,作者,内容,状态,浏览量,时创建间'."\r\n";
    $list = Test::orderBy('id','desc')->get(['id','title','author','images','description','status','view','created_at'])->toArray();
    $fp = fopen("$name.csv","a"); //打开csv文件，如果不存在则创建
    foreach ($list as $key => $value) {
        $data = $data.$value['id'].','.$value['title'].','.$value['author'].','.$value['images'].','.$value['description'].','.$value['status'].','.$value['view'].','.$value['created_at']."\r\n";
    }
    fwrite($fp,$data); //写入数据讲gbk转成utf8
    fclose($fp); //关闭文件句柄

    $config = array("host"=>"ip","username"=>"user","port"=>"22","password"=>"password");

    try {
        $sftp = new \sftpData($config);

        $re = $sftp->ssh2_dir_exits("/upload/$time");
        //如果目录存在直接上传
        if($re){
            $sftp->upftp("$name.csv",'/upload/'.$time.'/'.$name.'.csv');
        }else{
            $sftp->ssh2_sftp_mchkdir("/upload/$time");
            $sftp->upftp("$name.csv",'/upload/'.$time.'/'.$name.'.csv');
        }

        die('ok');
    } catch (\Exception $e) {
        die('连接失败！');
    }
}
