PHP中FTP上传文件和下载文件实例代码_PHP教程
一、LycFtpAbstract.class.php FTP基类
代码如下 | 复制代码 |
/* 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($this->ftpobj); } } } ?> |
二、LycFtpFtp.class.php 实现类
代码如下 | 复制代码 |
/* author:凹凸曼(lyc) /* email: jar-c@163.com /* time : 2011-04-22 /* */ require_once 'Lyc/Ftp/Abstract.class.php'; class Lyc_Ftp_Ftp extends Lyc_Ftp_Abstract{ public function __construct($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、LycException.class.php 异常基类
代码如下 | 复制代码 |
/* author:凹凸曼(lyc) /* email: jar-c@163.com /* time : 2011-04-22 /* */ class Lyc_Exception extends Exception{ } ?> |
四、LycFtpException.class.php FTP异常类
代码如下 | 复制代码 |
/* 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
