php实现通过ftp上传文件

 更新时间:2015年06月19日 10:26:11   投稿:hebedich   我要评论
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 ...
