A simple way of creating a pie chart from an array:
<?php
$Data="180-!-180-!-180";
$TempData=explode("-!-", $Data);
$tot=array_sum($TempData);
$len=count($TempData);
$prev=0;
for ($i=0; $i<$len; $i++)
{
$TempData[$i]=$prev+ceil(360*($TempData[$i]/$tot));
$prev=$TempData[$i];
}
$image = imagecreatetruecolor(300, 300);
for ($i=0; $i<$len; $i++) {
$r=rand(124, 255);
$g=rand(124, 255);
$b=rand(124, 255);
$colours[$i]=imagecolorallocate($image,$r-50,$g-20,$b-20);
$colours2[$i]=imagecolorallocate($image,$r,$g,$b);
}
for ($i = 155; $i > 150; $i--) {
$prev=0;
for($b=0;$b< $len; $b++){
imagefilledarc($image, 150, $i, 300, 150, $prev, $TempData[$b], $colours[$b], IMG_ARC_PIE);
$prev=$TempData[$b];
}
}
$prev=0;
for($b=0;$b< $len; $b++){
imagefilledarc($image, 150, 150, 300, 150, $prev, $TempData[$b], $colours2[$b], IMG_ARC_PIE);
$prev=$TempData[$b];
}
header('Content-type: image/png');
imagepng($image);
imagedestroy($image);
?>
