Saatlerdir uğraşıyorum hatayı bulamadım.

<?php
header("Content-type:image/gif");
$veri=array('sad','asdasd','verii','delii');
$pasta=array(50,85,25,35,67);
$toplam=array_sum($pasta);
$width=420;
$height=240;
$img=imagecreate(420,240);
$bg=imagecolorallocate($img,255,255,255);
$width=200;
$height=200;
$cx=$width/2;
$cy=$height/2;
$start=0;
for($i=0; $i<count($pasta);$i++) {
$e=round(($pasta[$i]/$toplam)*100,2);
$end=round(($e*360)/100);
$rgb1=rand(200,255);
$rgb2=rand(100,255); 
$rgb3=$rand(0,255);
$renk=imagecolorallocate($img,$rgb1,$rgb2,$rgb3);
imagefilledarc($img,$cx,$cy,$width,$height,$start,$start+$end,$renk,IMAGE_ARC_PIE);
imagefilledrectangle($img,250,50+($i*20),264,64+($i*20),$renk);
imagestring($img,3,276,52+($i*20),$veri[$i].'[%'.$e.']',$renk);
$start+=$end;
}
imagegif($img);
imagedestroy($img);
?>

EDİT:

Hatayı buldum kafayı yemekten kurduldum.
imagefilledarc($img,$cx,$cy,$width,$height,$start, $start+$end,$renk,IMAGE_ARC_PIE);
yerine
imagefilledarc($img,$cx,$cy,$width,$height,$start, $start+$end,$renk,IMG_ARC_PIE);

yazmam gerekiyormuş.
