<?php /** * 作用:FTP类( 拷贝、移动、删除文件/创建目录 ) * site http://www.jbxue.com */ class class_ftp { public $off; // 返回操作状态(成功/失败) public $conn_id; // FTP连接 /** * 方法:FTP连接 * @FTP_HOST -- FTP主机 * @FTP_PORT -- 端口 * @FTP_USER -- 用户名 * @FTP_PASS -- 密码 */ function __construct($FTP_HOST,$FTP_PORT,$FTP_USER,$FTP_PASS) { $this->conn_id = @ftp_connect($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 $path_div = count($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<=$path_div;$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 ?>
2、调用
<?php $ftp = new class_ftp('192.168.100.143',21,'user','pwd'); // 打开FTP连接 //$ftp->up_file('aa.txt','a/b/c/cc.txt'); // 上传文件 //$ftp->move_file('a/b/c/cc.txt','a/cc.txt'); // 移动文件 //$ftp->copy_file('a/cc.txt','a/b/dd.txt'); // 复制文件 //$ftp->del_file('a/b/dd.txt'); // 删除文件 $ftp->close(); // 关闭FTP连接 ?>
