คือว่ามีเรื่องจะรบกวนถามเกี่ยวกับการแก้ Fatal Error ของกราฟเส้นที่ใช้ pChart น่ะครับ

 


Topic : 071972

คือว่า ผมเขียนโค๊ดสร้างกราฟเส้น จาก pChart น่ะครับแล้วมันมี ปัญหา ตอนรันขึ้นมาว่า
Fatal error: Cannot redeclare class pData in C:\AppServ\www\project\files\pChart2.1.3\pChart2.1.3\class\pData.class.php on line 56

ก็เลย ไม่รูั้้ว่า Fatal Error มันคือ อะไร แล้วแก้ยังไง ขนาด Cannot redeclare ผมก็ยังไม่รู้เลยครับว่ามันคืออะไร
อันนี้ เป็นโค๊ค ที่ใช้รันครับ

Code (PHP)
<?
/* Include the pData class */
include_once("C:/AppServ/www/project/files/pChart2.1.3/pChart2.1.3/class/pData.class.php");
include("C:/AppServ/www/project/files/pChart2.1.3/pChart2.1.3/class/pDraw.class.php");
include("C:/AppServ/www/project/files/pChart2.1.3/pChart2.1.3/class/pImage.class.php");
include("C:/AppServ/www/project/files/pChart2.1.3/pChart2.1.3/class/pData.class.php");

/* Create the pData object */
$myData = new pData();
/* Connect to the MySQL database */
$db = mysql_connect("localhost", "root", "123456") or die ("Error :" .mysql_error());
mysql_select_db("pchart",$db);

/* Build the query that will returns the data to graph */
$Requete = "SELECT * FROM `measures`";
$Result = mysql_query($Requete,$db);
$timestamp=""; $temperature=""; $humidity="";
while($row = mysql_fetch_array($Result))
 {
/* Get the data from the query result */
$timestamp[] = $row["timestamp"];
$temperature[] = $row["temperature"];
$humidity[] = $row["humidity"];
}
/* Save the data in the pData array */
$myData->addPoints($timestamp,"Timestamp");
$myData->addPoints($temperature,"Temperature");
$myData->addPoints($humidity,"Humidity");

$myPicture = new pImage(700,230,$myData); 
$myPicture->setFontProperties(array("FontName"=>"C:/AppServ/www/project/files/pChart2.1.3/pChart2.1.3/fonts/Forgotte.ttf","FontSize"=>11));
$myPicture->setGraphArea(60,40,670,190);
$myPicture->drawScale();
$myPicture->drawSplineChart();
$myPicture->Render("basic3.png");
		

	?>

ส่วนอันนี้ เป็นโค๊ดที่ใช้ Include เข้ามา ที่มัน ฟ้อง Fatal Error น่ะครับ

มาๆ แก้ครับ เมื่อกี้ ผมดูผิดเองครับ
ใช้วิธีลบออกไปตัวหนึ่ง ได้ครับ
ได้ผลออกมาแล้วครับ ได้กราฟออกมาล่ะครับ

ขอบคุณมากๆครับ
ตอนนี้ก็คงแก้เรื่อง ภาษาไทยต่อไปครับ
