PHP to make 3D sector statistics and zoom operation Example _php instance

1, the use of PHP functions of the GD library to draw 3D sector statistics

<?php
Header ("Content-type", "text/html;charset=utf-8");
/* Sector Chart * *
$image = Imagecreatetruecolor (100, 100); /* Create Canvas * *
/* Set the color required for the canvas * *
$white = Imagecolorallocate ($image, 0xff,0xff,0xff);
$gray = Imagecolorallocate ($image, 0xc0, 0xc0, 0xc0);
$darkgray = Imagecolorallocate ($image, 0x90, 0x90, 0x90);
$navy = Imagecolorallocate ($image, 0x00, 0x00, 0x80);
$darknavy = Imagecolorallocate ($image, 0x00, 0x00, 0x50);
$red = Imagecolorallocate ($image, 0xFF, 0x00, 0x00);
$darkred = Imagecolorallocate ($image, 0x90, 0x00, 0x00);
/* Fill Background color * *
Imagefill ($image, 0, 0, $white);
/*3d Making * *
for ($i = $i > $i-)
{
Imagefilledarc ($image, $i, M, -160, $darknavy, Img_arc_pie);
Imagefilledarc ($image, $i, M, N, $darkgray, Img_arc_pie);
Imagefilledarc ($image, $i, M, N, $darkred, Img_arc_pie);
}
/* Draw ellipse arc and fill/*
Imagefilledarc ($image, M, -160, $darknavy, Img_arc_pie);
Imagefilledarc ($image, $darkgray, M, Img_arc_pie);;
Imagefilledarc ($image, N, $darkred, Img_arc_pie), and
/* Draw String * *
Imagestring ($image, 3,,, "30%", $white);
Imagestring ($image, 3, A, "60%", $white);
Imagestring ($image, 3,,, "10%", $white);
/* Output Image * *
Header ("Content-type:image/png");
Imagepng ($image);
/* Release of resources * *
Imagedestroy ($image);
?>
