PHP针对ftp文件的操作方法,如果是只操作一个ftp,可以使用里面的单利模式,

不需要每次都去实例化,我的项目中需要去链接很多个ftp服务器;

所以需要多次去连接和关闭;

ftp = @ftp_connect($config['ftp_ip'],$config['ftp_port']) or die("FTP connection fail");       //登录验证       @ftp_login($this->ftp,$config['ftp_username'],$config['ftp_password']);       //是否开启被动模式        if (isset($config['ftp_pasv']))        {            @ftp_pasv($this->ftp,true);        }    }    /**     * Created by PhpStorm.     * function: getInstance     * Description:公有的静态方法     * User: Xiaoxie     * Email 736214763@qq.com     * @return FtpFile|null     *     */    static public function getInstance($config){        if(!(self::$_instance instanceof self)){            self::$_instance = new FtpFile($config);        }        return self::$_instance;    }    /**     * Created by PhpStorm.     * function: up_file     * Description:上传文件     * User: Xiaoxie     * Email 736214763@qq.com     * @param $path 本地路径     * @param $newpath  若目标目录不存在则新建     * @param bool $type     *     */    function up_file($path,$newpath,$type=true)    {        if($type) $this->dir_mkdirs($newpath);        $this->off = @ftp_put($this->ftp,$newpath,$path,FTP_BINARY);        if(!$this->off)        {            return "文件上传失败,请检查权限及路径是否正确!";        }else{            //删除文件            unlink($path);            return true;        }    }    /**     * Created by PhpStorm.     * function: uploadFile     * Description:多文件上传     * User: Xiaoxie     * Email 736214763@qq.com     * @param array $files     * @param bool $type     * @return bool|void     *     */    public function uploadFile($files=[],$type=true)    {        if (is_array($files))        {            foreach ($files as $key=>$file)            {                if($type)                {                    $this->dir_mkdirs($file);                }                $this->off = @ftp_put($this->ftp,$file,$key,FTP_BINARY);                if(!$this->off)                {                     logs('ftp.txt',date('Y-m-d H:i:s').$file."文件上传错误");                }else{                    //删除文件                    unlink($key);                   // return true;                }            }        }        if(!$this->off)        {            //logs函数自定义日志            logs('ftp.txt',date('Y-m-d H:i:s').$file."文件上传错误");            return false;        }else{            return true;        }    }    /**     * Created by PhpStorm.     * function: move_file     * Description:移动文件 修改文件名     * User: Xiaoxie     * Email 736214763@qq.com     * @param $path 原路径     * @param $newpath 若目标目录不存在则新建     * @param bool $type     *     */    function move_file($path,$newpath,$type=true)    {        if($type) $this->dir_mkdirs($newpath);        $this->off = @ftp_rename($this->ftp,$path,$newpath);        if(!$this->off) {            return "文件移动失败,请检查权限及原路径是否正确!";        }else{            return true;        }    }    /**     * Created by PhpStorm.     * function: copy_file     * Description:复制文件     * User: Xiaoxie     * Email 736214763@qq.com     * @param $path原路径     * @param $newpath 新路径     * @param bool $type 若目标目录不存在则新建     *     */    function copy_file($path,$newpath,$type=true)    {        $downpath = "/var/www/temp.txt";        $this->off = @ftp_get($this->ftp,$downpath,$path,FTP_BINARY);// 下载         if(!$this->off)         {            return "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);    }    /**     * Created by PhpStorm.     * function: del_file     * Description:删除文件     * User: Xiaoxie     * Email 736214763@qq.com     * @param $path     *     */    function del_file($path)    {        $this->off = @ftp_delete($this->ftp,$path);        if(!$this->off){            return false;        }    }    /**     * Created by PhpStorm.     * function: dir_mkdirs     * Description:生成目录     * User: Xiaoxie     * Email 736214763@qq.com     * @param $path 路径     *     */    function dir_mkdirs($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->ftp,$val) == FALSE)            {                $tmp = @ftp_mkdir($this->ftp,$val);                if($tmp == FALSE)                {                                        exit;                }                @ftp_chdir($this->ftp,$val);            }        }        for($i=1;$i<=$path_div;$i++)         // 回退到根         {            @ftp_cdup($this->ftp);        }    }    /**     * Created by PhpStorm.     * function: close     * Description:关闭链接     * User: Xiaoxie     * Email 736214763@qq.com     *     */    public function close()    {        @ftp_close($this->ftp);    }    /**     * 关闭链接     *单例模式打开析构方法     */    public function __destruct()    {        // TODO: Implement __destruct() method.        //@ftp_close($this->ftp);    }}

lavarel中直接调用;

单例模式调用:

FtpFile::getInstance($this->data)->up_file($location_file,$remote_file);

不是单例模式调用;

$ftp = new FtpFile($this->data);$ftp->uploadFile($filearr);$ftp->close();
