PHP FTP操作类代码( 上传、拷贝、移动、删除文件/创建目录)

复制代码 代码如下:

class class_ftp
{
    public $off; // 返回操作状态(成功/失败)
    public $conn_id; // FTP连接
   
    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
    }
   
    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！";
    }
   
    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！";
    }
   
    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);
    }
   
    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！";
    }
   
    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);
        }
    }
   
    function close()
    {
        @ftp_close($this->conn_id);
    }
}// class class_ftp end
