php实现通过ftp上传文件

大概原理

遍历项目中的所有非排除文件，然后获取 文件修改时间晚于文件上一次修改时间 的文件

然后将这些文件，通过ftp上传到对应的目录

具体代码如下:

因为只是工具，代码很乱，见谅

    <?php
    error_reporting(7);
    if ($_SERVER['SERVER_ADDR'])exit;//禁止在web服务器下运行
    $_GET['exclude'] = array('number.txt','uploads','Zend','docs','cache','You','managesdk'); //排除上传目录,定义为全局变量
    $fileobj = new FilerFile();
    $path = "/data/longtu/"; //项目目录的根目录
    $files = $fileobj->Zip($path); //过滤出最新的修改文件
    $path = str_replace("/data/longtu/","",$path);
    $config = array(
      'hostname' => 'xxx.xxx.xx.xxx', //ftp服务器 地址
      'username' => 'xxx',     //ftp用户
      'password' => '?xxxxxxxxxxx', //ftp密码
      'port' => 21         //端口
    );
    $ftp = new Ftp();
    $ftp->connect($config);       //链接服务器
    //$a=$ftp->filelist();
    $LOCAL_ROOT = realpath(dirname(__DIR__)."/../../");
    chdir($LOCAL_ROOT);
    foreach ($files as $k=>$v){
      $f = $path.$v;
      $tmp = $ftp->upload($f, $f);
      if($tmp){
      echo "upload $f -> success \n";
      }
    }
    //$ftp->download('ftp_upload.log','ftp_download.log');
    //
    //$ftp->upload('ftp_err.log','ftp_upload.log');
    //$ftp->download('ftp_upload.log','ftp_download.log');
    /*
