放在vendor文件夹下,调用时页面上:

public function index(){
        set_time_limit(0);
        ini_set(‘memory_limit‘,‘-1‘);
        $config=array(
            ‘hostname‘=>‘127.0.0.1‘,  //ip
            ‘username‘=>‘root‘,
            ‘password‘=>‘root‘,
            ‘port‘=>‘21‘,  //端口号
        );
        vendor(‘ftp‘);
        $ftp=new Ftp();
        $conn=$ftp->connect($config);
        $res=$ftp->filelist(‘file_name‘);  //需要获取的文件夹名称
     return $res;
}
