     $this->width=$w;
 $this->height=$h;
}

function connectdb()
{
     $this->server=mysql_connect($this->host, $this->username, $this->password);
     $this->selectdb=mysql_select_db($this->db, $this->server);
}

function createimg($typeb=" ", $sourceb=" ", $srcx2b=" ", $srcy2b=" ")
{
      $this->type=$typeb;
     if ($this->type=="truecolor")
	{
	 $this->funct="imagecreate".$this->type;
         $this->img=$this->funct($this->width, $this->height);
	}

         $this->img=$this->funct($this->source, $this->srcx2, $this->srcy2, $this->width, $this->height);
	}
     else if ($this->type=" ")
	{
         $this->funct="imagecreate";
         $this->img=imagecreate($this->width, $this->height);
	}
     else
	{
         $this->funct="imagecreatefrom".$this->type;
         $this->img=$this->funct($source);
	}
}
    
function coloralloc($a, $b, $c)
{
     $this->x=$a;
 $this->y=$b;
 $this->z=$c;
     $this->alloc=imagecolorallocate($this->img, $this->x, $this->y, $this->z);
}

    function text($txt1, $txt2, $txt3, $txt4, $txt5, $txt6, $txt7)
{

     $this->string=imagettftext($this->img, $this->size, $this->angle, $this->x2, $this->y2, $this->color, $this->font, $this->text);
}

function destruct2()
{
     imagepng($this->img);
     imagedestroy($this->img);
}


}

class Pie extends Graphs
{
  private $datas1;
  private $datas2;
  private $keys;
  private $flag;
  private $num;
  private $info;

  function tabledata($arr1, $arr2)
{
      $this->datas1=$arr1;
  $this->datas2=$arr2;
      
  for ($i=0; $i<count($this->datas1); $i+=2)
	{
	 $i=$j;
         $this->keys[]=$this->datas[$j];
	 $this->flag[]=$this->datas[$j++];
	}
  
  foreach ($this->datas2 as $data)
	{
         $this->num +=(int) $data;
	}
      
  foreach ($this->datas2 as $data2)
	{
         $this->info[] = ($data2/$this->num)*360;
	} 
}
}

$graph=new Pie("localhost", "root", "jd2008", "graphexample", "100", "100");
$graph->connectdb();
$graph->createimg();
$graph->coloralloc("200", "100", "100");
$graph->destruct2();
?>

 

i get this output:

Quite possibly. Are you using php5? Before php5 the constuctor function had the same name as the class, rather than being called __construct.
