1. Use PHP to operate FTP-usage

2. FTP upload class (ftp.php)

conn_id = @ftp_connect($FTP_HOST,$FTP_PORT) or die("FTP服务器连接失败"); @ftp_login($this->conn_id,$FTP_USER,$FTP_PASS) or die("FTP服务器登陆失败"); @ftp_pasv($this->conn_id,1); // 打开被动模拟 } /** * 方法：上传文件 * @path -- 本地路径 * @newpath -- 上传路径 * @type -- 若目标目录不存在则新建 */ function up_file($path,$newpath,$type=true) { if($type) $this->dir_mkdirs($newpath); $this->off = @ftp_put($this->conn_id,$newpath,$path,FTP_BINARY); if(!$this->off) echo "文件上传失败,请检查权限及路径是否正确！"; } /** * 方法：移动文件 * @path -- 原路径 * @newpath -- 新路径 * @type -- 若目标目录不存在则新建 */ function move_file($path,$newpath,$type=true) { if($type) $this->dir_mkdirs($newpath); $this->off = @ftp_rename($this->conn_id,$path,$newpath); if(!$this->off) echo "文件移动失败,请检查权限及原路径是否正确！"; } /** * 方法：复制文件 * 说明：由于FTP无复制命令,本方法变通操作为：下载后再上传到新的路径 * @path -- 原路径 * @newpath -- 新路径 * @type -- 若目标目录不存在则新建 */ function copy_file($path,$newpath,$type=true) { $downpath = "c:/tmp.dat"; $this->off = @ftp_get($this->conn_id,$downpath,$path,FTP_BINARY);// 下载 if(!$this->off) echo "文件复制失败,请检查权限及原路径是否正确！"; $this->up_file($downpath,$newpath,$type); } /** * 方法：删除文件 * @path -- 路径 */ function del_file($path) { $this->off = @ftp_delete($this->conn_id,$path); if(!$this->off) echo "文件删除失败,请检查权限及路径是否正确！"; } /** * 方法：生成目录 * @path -- 路径 */ function dir_mkdirs($path) { $path_arr = explode('/',$path); // 取目录数组 $file_name = array_pop($path_arr); // 弹出文件名 $path_p = count($path_arr); // 取层数 foreach($path_arr as $val) // 创建目录 { if(@ftp_chdir($this->conn_id,$val) == FALSE) { $tmp = @ftp_mkdir($this->conn_id,$val); if($tmp == FALSE) { echo "目录创建失败,请检查权限及路径是否正确！"; exit; } @ftp_chdir($this->conn_id,$val); } } for($i=1;$i<=$path_p;$i++) // 回退到根 { @ftp_cdup($this->conn_id); } } /** * 方法：关闭FTP连接 */ function close() { @ftp_close($this->conn_id); } } // class class_ftp end

Example:

/************************************** 测试 *********************************** $ftp = new ftp('222.13.67.42',21,'hlj','123456'); // 打开FTP连接 $ftp->up_file('aa.wav','test/13548957217/bb.wav'); // 上传文件 //$ftp->move_file('aaa/aaa.php','aaa.php'); // 移动文件 //$ftp->copy_file('aaa.php','aaa/aaa.php'); // 复制文件 //$ftp->del_file('aaa.php'); // 删除文件 $ftp->close(); // 关闭FTP连接 //******************************************************************************/
