PHP图片上传类带图片显示

这是一个PHP的文件上传类带图片显示的.其实做成函数就可以了.不过还是做成类好玩一点.~~~~
本来应该用JS来验证上传文件类型的.但懒得做了.

无标题文档

Class upload
{
  var $upload_name;
  var $upload_tmp_address;
  var $upload_server_name;
  var $upload_filetype ;
  var $file_type;
  var $file_server_address;
  var $image_w=900;  //要显示图片的宽
  var $image_h=350;  //要显示图片的高
  var $upload_file_size;
  var $upload_must_size= 50000; //允许上传文件的大小，自己设置
  function upload_file()
  {
   $this->upload_name = $_FILES["file"]["name"];    //取得上传文件名
   $this->upload_filetype = $_FILES["file"]["type"];
   $this->upload_server_name = date("Y_m_dH_i_s").$this->upload_name;
   $this->upload_tmp_address = $_FILES["file"]["tmp_name"];    //取得临时地址
   $this->file_type = array("image/gif","image/pjpeg");  //允许上传文件的类型
   $this->upload_file_size = $_FILES["file"]["size"];  //上传文件的大小
   if(in_array($this->upload_filetype,$this->file_type))
   { if($this->upload_file_size < $this->upload_must_size)
    {
        echo("上传成功，谢谢支持");
     $this->file_server_address = "D:usrwwwhtmlupload/".$this->upload_server_name;
        move_uploaded_file($this->upload_tmp_address,$this->file_server_address);//从TEMP目录移出
        echo("file_server_address width=$this->image_w height=$this->image_h/>");  //显示图片


     }
     else
     {
      echo("文件容量太大");
     }
   }
   else
   {
    echo("不支持此文件类型，请重新选择");
   }

  }

}
$dd = new upload;
$dd->upload_file();
