PHP实现FTP上传文件和下载文件

昨天写了一个PHP实现FTP的上传、下载文件，这哈又来晒哈

目录文件结构按照下图建

文件源码如下：

一、Lyc\Ftp\Abstract.class.php   FTP基类

<?php
    /*  author:凹凸曼(lyc)
    /*  email: jar-c@163.com
    /*  time : 2011-04-22
    */ 

abstract class Lyc_Ftp_Abstract {

    protected $ftpobj=null;
    protected $host='';
    protected $user='anonymous';
    protected $pwd='';
    protected $mode=FTP_BINARY;
    protected $port=21;
    protected $timeout=90;

    protected $pasv=TRUE;

    protected function init(){

    }
    /**
    * 建立ftp连接
    *
    */
    protected function connect(){
       $this->ftpobj=@ftp_connect($this->host,$this->port,$this->timeout);
       if(null==$this->ftpobj){
        require_once 'Lyc/Ftp/Exception.class.php';
       throw new Lyc_Ftp_Exception("FTP ERROR : Couldn't connect to $this->host");
       }
    }
    /**
    * 建立ssl ftp连接
    *
    */
    protected function connectSsl(){
       $ftpobj=@ftp_ssl_connect($this->host,$this->port,$this->timeout);
       if(null==$ftpobj){
        require_once 'Lyc/Ftp/Exception.class.php';
       throw new Lyc_Ftp_Exception("FTP ERROR : Couldn't connect to $this->host");
       }
    }
    /**
    * 登录验证ftp 及设置模式
    *
    */
    protected function login(){

        if(@ftp_login($this->ftpobj,$this->user,$this->pwd)){
            ftp_pasv($this->ftpobj,$pasv);

        }else{
            require_once 'Lyc/Ftp/Exception.class.php';
            throw new Lyc_Ftp_Exception("FTP ERROR : Couldn't login to $this->host");
        }
    }
    /**
    * 上传文件
    *
    */
    public function upload($remotefile,$localfile){

    }
    /**
    * 下载文件
    *
    */
    public function download($localfile,$remotefile){

    }
    /**
    * 关闭连接
    *
    */
    public function close(){
        if(is_string($this->ftpobj)){
            ftp_close($this->ftpobj);
        }
    }

}
?>

 
二、Lyc\Ftp\Ftp.class.php   实现类

<?php
    /*  author:凹凸曼(lyc)
    /*  email: jar-c@163.com
    /*  time : 2011-04-22
    /*
    */
require_once 'Lyc/Ftp/Abstract.class.php';
class Lyc_Ftp_Ftp extends Lyc_Ftp_Abstract{

    public function __construct($host,$user,$pwd,$mode=FTP_BINARY,$port=21,$timeout=90,$pasv=TRUE){
        $this->host=$host;
        $this->user=$user;
        $this->pwd=$pwd;
        $this->mode=$mode;
        $this->port=$port;
        $this->timeout=$timeout;
        $this->pasv=$pasv;
        $this->init();

    }
    protected function init(){

            $this->connect();
            $this->login();

    }
    /**
    * 上传文件
    *
    */
    public function upload($remotefile,$localfile){

       $res=ftp_nb_put($this->ftpobj,$remotefile,$localfile,$this->mode,ftp_size($this->ftpobj,$remotefile));
       while($res==FTP_MOREDATA){
           $res=ftp_nb_continue($this->ftpobj);
       }
       if($res!=FTP_FINISHED){
           return FALSE;
       }
       return TRUE;
    }
    /**
    * 下载文件
    *
    */
    public function download($localfile,$remotefile){
        ftp_set_option($this->ftpobj,FTP_AUTOSEEK,FALSE);
        $res=ftp_nb_get($this->ftpobj,$localfile,$remotefile,$this->mode,ftp_size($this->ftpobj,$localfile));
        while($res==FTP_MOREDATA){
            $res=ftp_nb_continue($this->ftpobj);
        }
        if($res!=FTP_FINISHED){
            return FALSE;
        }
        return TRUE;
    }
}
?>

三、Lyc\Exception.class.php  异常基类

<?php
    /*  author:凹凸曼(lyc)
    /*  email: jar-c@163.com
    /*  time : 2011-04-22
    /*  

    */
    class Lyc_Exception extends Exception{

    }
?>

四、Lyc\Ftp\Exception.class.php  FTP异常类

<?php
    /*  author:凹凸曼(lyc)
    /*  email: jar-c@163.com
    /*  time : 2011-04-22
    */
require_once 'Lyc/Exception.class.php';
class Lyc_Ftp_Exception extends Lyc_Exception{

}
?>

五、测试区

<?php 
   /**
    * 上传文件
    *
    */
    public  function uploadTest(){
        require_once 'Lyc/Ftp/Ftp.class.php';
        $host=23.64.41.13';     //主机
        $user='tguser';                //用户名
        $pwd="";                         //密码   端口默认21 也可改
        $ftp=new Lyc_Ftp_Ftp($host,$user,$pwd);
        $res=$ftp->upload('test.rar',"F:\\wwwroot\\testarea\\Lyc\\Test\\test.rar");
        if(!$res){
            echo " upload failure";
        }

    }

    public function downloadTest(){
        require_once 'Lyc/Ftp/Ftp.class.php';
        $host=33.64.41.135';
        $user='tguser';
        $pwd="";
        $ftp=new Lyc_Ftp_Ftp($host,$user,$pwd);
        $res=$ftp->download("c:\\test.rar","test.rar");
        if(!$res){
            echo "download failure";
        }

    }

对应上面的实现FTP的功能都基础的，还有更大的比如FTP目录列表及文件，还有改变目录，选择需要下载的文件，

上面的可以扩展一下就行了
