我正在将我的 MySQL 数据库数据解析为融合图表代码并绘制饼图...但不幸的是有些字符未显示...请帮助解决此问题... 这是我的代码:
<?php
include("FusionCharts/FusionCharts.php");
include("special_db_connect.php");
?>
<HTML>
<HEAD>
<TITLE>
Exam Result Analysis
</TITLE>
<?php
?>
<script LANGUAGE="Javascript" SRC="FusionCharts/FusionCharts.js"></SCRIPT>
<style type="text/css">
<!--
body {
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
}
.text{
font-family: Arial, Helvetica, sans-serif;
font-size: 12px;
}
-->
</style>
</HEAD>
<BODY>
<CENTER>
<?php
// Connect to the DB
$link = connectToDB();
//Generate the chart element
$strXML = "<chart caption='Academic year 2010/2011 results' subCaption='By Grades' pieSliceDepth='30' showBorder='1' formatNumberScale='0' numberSuffix=' Students'>";
// Fetch all factory records
$strQuery = "SELECT grade, COUNT(*) 'No_Of_grades' FROM std_results WHERE course_code ='CSC113A' GROUP BY grade";
$result = mysql_query($strQuery) or die(mysql_error());
//Iterate through each factory
if ($result) {
while($ors = mysql_fetch_array($result)) {
//Generate <set label='..' value='..' />
$strXML .= "<set label='" . $ors['grade'] . "' value='" . $ors['No_Of_grades'] . "' />";
}
}
//Finally, close <chart> element
$strXML .= "</chart>";
//Create the chart - Pie 3D Chart with data from $strXML
echo renderChart("FusionCharts/Pie3D.swf", "", $strXML, "Results", 600, 300, false, false);
echo "</br></br>";
mysql_close($link);
?>
</CENTER>
</BODY>
</HTML>
输出饼图
...这是我的代码之上
{$strQuery = "SELECT grade, COUNT(*) 'No_Of_grades' FROM std_results WHERE course_code ='CSC113A' GROUP BY grade";}
:此代码在 phpmyadmin 中的结果:
实际上此表值将解析为饼图。在这里您可以在等级列中看到 A+、C+ 值...问题是那些字符串未显示在饼图中。{请访问上面的饼图图像}。实际上 A+ 和 C+ 显示没有 '+' 字符。{但是 '-',C-,A- 字符显示}..这对我来说是个问题..我该如何解决这个问题...{提醒上面的代码运行良好..没问题，唯一的问题是不显示“+”字符。}**
最佳答案
尝试用 %2B 对符号 + 进行编码:
$strXML .= "<set label='" . str_replace('+', '%2B', $ors['grade']) . "' value='" . $ors['No_Of_grades'] . "' />";
