We can create Pie Chart using the following PHP code:
<?php
$n1 = 10; //Set your values here as either static or dynamic
$n2 = 5;
$n3 = 10;
$n4 = 5;
$n5 = 10;

$image = imagecreate(500, 600); // Create a new 500 x 600 image

// SET UP SOME COLOURS
$yellow = imagecolorallocate($image, 255, 255, 0); // create color R=255, G=255, B=0
$cyan = imagecolorallocate($image, 0, 255, 255); // create color R=0, G=255, B=255
$red = imagecolorallocate($image, 255, 0, 0); // create color red
$blue = imagecolorallocate($image, 0, 0, 255); // create color blue
$lime = imagecolorallocate($image, 0, 255, 0); // create color lime
$magenta = imagecolorallocate($image, 255, 0, 255); // create color magenta

// Add up input data to find total amount.
$total = $n1 + $n2 + $n3 + $n4 + $n5;

$startAngle = 0;
$endAngle = $StartAngle + 360 * $n1 / $total;
ImageFilledArc($image, 250, 350, 200, 200, $startAngle, $endAngle, $red, IMG_ARC_PIE);

$startAngle = $endAngle;
$endAngle = $endAngle + 360 * $n2 / $total;
ImageFilledArc($image, 250, 350, 200, 200, $startAngle, $endAngle, $blue, IMG_ARC_PIE);

$startAngle = $endAngle;
$endAngle = $endAngle + 360 * $n3 / $total;
ImageFilledArc($image, 250, 350, 200, 200, $startAngle, $endAngle, $lime, IMG_ARC_PIE);

$startAngle = $endAngle;
$endAngle = $endAngle + 360 * $n4 / $total;
ImageFilledArc($image, 250, 350, 200, 200, $startAngle, $endAngle, $cyan, IMG_ARC_PIE);

$startAngle = $endAngle;
$endAngle = $endAngle + 360 * $n5 / $total;
ImageFilledArc($image, 250, 350, 200, 200, $startAngle, $endAngle, $magenta, IMG_ARC_PIE);

header ("Content-type: image/png");
ImagePNG($image); // Save image to file.
ImageDestroy($image); // Cleanup memory
?>
