自动保存远程图片类功能是用户可以初始化要采集图片的地址，采集下来的图片保存的路径，如果路径存在就直接下载远程图片地址，否则自动创建目录并且保存图片。

*/
class getromatePic{
  var $savaDir ='pic/';
  var $filePath ='http://www.111cn.net/banner/banner.gif';
  var $fileName ='111cn.net.gif';

  function __construct() {
   $this->isdir();
  }


  function isdir()
  {
   if( !is_dir( $this->savaDir ) )
   {
    if( ! mkdir( $this->savaDir ) )
    {
     exit('目录不存并且没有写的权限');
    }
   }
   $this->autoGetRemoteFile();
  }

  function autoGetRemoteFile()
  {
   $content = file_get_contents($this->filePath);
   if( $content )
   {
    $hold = fopen($this->savaDir.$this->fileName,'w+');
    if( fwrite($hold,$content) )
    {
     echo '图片自动采集成功';
     fclose($hold);
    }
    else
    {
     echo '保存失败';
    }
   }
   else
   {
    echo '远程图路不正确';
   }
  }
}

//类调用方法

new getromatePic();
//由于使用的构造函数所以我们只需要创建类，其它的会自动执行，
