A good ftp operation class that can complete operations such as copying, moving, deleting files, creating directories, etc. Friends in need can refer to it.

1. FTP operation class

<?php
/**
* 作用:FTP类( 拷贝、移动、删除文件/创建目录 )
* site http://bbs.it-home.org
*/
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. Call example

<?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
?>
