Menampilkan Grafik Pie dengan PHP dan MySQL

Menampilkan Grafik Pie dengan PHP dan MySQL | Berikut ini saya akan memberikan tips kepada anda bagaimana menampilkan Grafik dalam bentuk Pie menggunakan PHP dan MySQL. Silahkan anda membuat database nya menggunakan tabel dibawah, atau anda dapat memodifikasi sesuai kebutuhan.
CREATE TABLE `tabelpengunjung` (
`nomor` int(5) NOT NULL auto_increment,
`nama` varchar(50) NOT NULL,
`tanggal` date NOT NULL,
PRIMARY KEY  (`nomor`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=9 ;
INSERT INTO `tabelpengunjung` (`nomor`, `nama`, `tanggal`) VALUES
(1, ‘Desrizal’, ’2010-05-04′),
(2, ‘Nurmi’, ’2010-05-11′),
(3, ‘Batman’, ’2010-05-18′),
(4, ‘Andi’, ’2010-06-15′),
(5, ‘Desrizal’, ’2010-07-13′),
(6, ‘Superman’, ’2010-07-06′),
(7, ‘Tari’, ’2010-08-11′),
(8, ‘Nurmi’, ’2010-08-17′);


selanjutnay copi paste script dibawah dan buatlah dengan nama
pie.php
<?php
mysql_connect(“localhost”,”root”,”");
mysql_select_db(“test”);
$data = “”;
$label = “”;
$query = mysql_query(“select count(*) as jumlah, monthname(tanggal) as bulan

?>
nah scipt diatas digunakan utuk membuat grafik pie. kemudian kita akan membuat menampilkan grafik pie tersebut didalam file lian dengan nama
tampilkangrafik.html
<img src=pie.php>
nah silahkan jalankan script tersebut di webserver kesayangan anda.
Selamat Mencoba;
