在php中我们可以利用ftp_connect相关函数实现文件上传与下载功能,其实就是ftp客户端一样的操作,下面我来给大家介绍如何利用php来实现

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

1. <?php
2. error_reporting(7);
3. if ($_SERVER['SERVER_ADDR'])exit;//禁止在web服务器下运行
4. $_GET['exclude'] = array('number.txt','uploads','Zend','docs','cache','You','managesdk'); //排除上传目录,定义为全局变量
5. $fileobj = new FilerFile();
6. $path = "/data/longtu/"; //项目目录的根目录
7. $files = $fileobj->Zip($path); //过滤出最新的修改文件
8. $path = str_replace("/data/longtu/","",$path);
9. $config = array(
10. 'hostname' => 'xxx.xxx.xx.xxx', //ftp服务器 地址
11. 'username' => 'xxx', //ftp用户
12. 'password' => '?xxxxxxxxxxx', //ftp密码
13. 'port' => 21 //端口
14. );
15. $ftp = new Ftp();
16. $ftp->connect($config); //链接服务器
17. //$a=$ftp->filelist();
18. $LOCAL_ROOT = realpath(dirname(__DIR__)."/../../");
19. chdir($LOCAL_ROOT);
20. foreach ($files as $k=>$v){
21. $f = $path.$v;
22. $tmp = $ftp->upload($f, $f);
23. if($tmp){
24. echo "upload $f -> success \n";
25. }
26. }
27. //$ftp->download('ftp_upload.log','ftp_download.log');
28. //
29. //$ftp->upload('ftp_err.log','ftp_upload.log');
30. //$ftp->download('ftp_upload.log','ftp_download.log');
31. /*

33. *
34. * $dir = "/test";
35. if(@ftp_chdir($conn, $dir))
36. 判断是否为文件夹
