php实现通过ftp上传文件
发布:smiling 来源: PHP粉丝网 添加日期:2021-05-28 22:11:34 浏览: 评论:0
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
- <?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');
- /*
- *
- *
- * $dir = "/test";
- if(@ftp_chdir($conn, $dir))
- 判断是否为文件夹
- * Enter description here ...
- * @author Administrator
