本篇文章主要介绍PHP利用ftp_connect函数实现文件上传下载功能，感兴趣的朋友参考下，希望对大家有所帮助。
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');
/*

if(@ftp_chdir($conn, $dir))
