主要包括三个文件:
1、view.php是调用程序。
2、chart.php是用来生成图表的程序。
3、gbtoutf8.php是用来中文解码的(注:已解决中英文混合不能正常显示的问题)

1、view.php
<?
include("gbtoutf8.php");
?>
<html>
<head>
<title>  </title>
<meta name="Author" content="XIANG Li">
</head>
<?
/*此处数据可从数据库中取得*/
$aStr = "IT,PC,Phone,Sever,Passport,Software";
$aSoft = "Win2000,Win98,Office,Foxmail,Outlook";
$aHard = gb2utf8("地板,窗户,玻璃,桌子,灯管,植被");
$title1 = gb2utf8('2002年IT维护report');
$title2 = gb2utf8('2002年软件维护report');
$title3 = gb2utf8('2002年固定资产report');
?>
<body>
<div align="center">
<table>
<tr>
    <td><input type="image" src="./chart.php?aStr=<?=$aStr?>&title=<?=$title1?>"></td>
</tr>
<tr><td> </td></tr>
<tr>
    <td><input type="image" src="./chart.php?aStr=<?=$aSoft?>&title=<?=$title2?>"></td>
</tr>
<tr><td> </td></tr>
<tr>
    <td><input type="image" src="./chart.php?aStr=<?=$aHard?>&title=<?=$title3?>"></td>
</tr>
</table></div>
</body>
</html>

2、chart.php

  }

  ImagePNG($im);
  ImageDestroy($im);
?>
