在php中我們也有可以直接來操作ftp，然後利用php實現與ftp一樣的文件上傳與下載文件的功能哦，下面我來介紹一個完整的實例。
一、LycFtpAbstract.class.php FTP基類
代碼如下 復制代碼 <?php
/* author:凹凸曼(lyc)
/* email:
[email protected] /* 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連接
*
*/
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連接
*
*/
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 $this->host");
}
}
/**
* 登錄驗證ftp 及設置模式
*
*/
protected function login(){
if(@ftp_login($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 $this->host");
}
}
/**
* 上傳文件
*
*/
public function upload($remotefile,$localfile){
}
/**
* 下載文件
*
*/
public function download($localfile,$remotefile){
}
/**
* 關閉連接
*
*/
public function close(){
if(is_string($this->ftpobj)){
ftp_close($this->ftpobj);
}
}
}
?>
二、LycFtpFtp.class.php 實現類
代碼如下 復制代碼 <?php
/* author:凹凸曼(lyc)
/* email:
[email protected] /* time : 2011-04-22
/*
*/
require_once 'Lyc/Ftp/Abstract.class.php';
class Lyc_Ftp_Ftp extends Lyc_Ftp_Abstract{
public function __construct($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();
$this->login();
}
/**
* 上傳文件
*
*/
public function upload($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($res!=FTP_FINISHED){
return FALSE;
}
return TRUE;
}
/**
* 下載文件
*
*/
public function download($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、LycException.class.php 異常基類
代碼如下 復制代碼 <?php
/* author:凹凸曼(lyc)
/* email:
[email protected] /* time : 2011-04-22
/*
*/
class Lyc_Exception extends Exception{
}
?>
四、LycFtpException.class.php FTP異常類
代碼如下 復制代碼 <?php
/* author:凹凸曼(lyc)
/* email:
[email protected] /* time : 2011-04-22
*/
require_once 'Lyc/Exception.class.php';
class Lyc_Ftp_Exception extends Lyc_Exception{
}
?>
五、測試區
代碼如下 復制代碼
<?php
/**
* 上傳文件
*
*/
public function uploadTest(){
require_once 'Lyc/Ftp/Ftp.class.php';
$host=23.64.41.13'; //主機
$user='tguser'; //用戶名
$pwd=""; //密碼 端口默認21 也可改
$ftp=new Lyc_Ftp_Ftp($host,$user,$pwd);
$res=$ftp->upload('test.rar',"F:wwwroottestareaLycTesttest.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";
}
}
