在谷歌饼图中使用php变量(Use php variable in google pie chart)

 我想在Google图表中使用我的PHP变量，但图表无法读取我的PHP标记。 正如您可以看到下面的代码，我将PHP变量放在脚本中。 （我在代码顶部定义的PHP变量，结果是正确的）。 我的代码出了什么问题？ 这有什么解决方案吗？ 如果需要，请向我询问更多信息。 谢谢。  
<script type="text/javascript">
  google.charts.load('current', {'packages':['corechart']});
  google.charts.setOnLoadCallback(drawChart);
  function drawChart() {

    var data = google.visualization.arrayToDataTable([
      ['Order', 'Amount'],
      ['Completed',     '<?php echo$completed ?>'],
      ['New',      '<?php echo$new ?>']
    ]); 

    var options = {
      title: 'Total Order ' + <?php echo$total; ?>
    };

    var chart = new google.visualization.PieChart(document.getElementById('piechart'));

    chart.draw(data, options);
  }
</script>

I want to use my PHP variable in Google chart,but the chart couldn't read my PHP tag. As you can see the code below I put my PHP variable in the script. (The PHP variable I have defined at top of the code and the result is correct). What's wrong with my code ? Is there any solution for this ? Do ask me for more information if needed. Thank you.

 在更多地讨论之后，我意识到Fraser指出了什么 - 这种方法并不总是有效，因为我不能指望GUID可以在新的CMake上运行。 所以我选择了我在CMake邮件列表上看到的建议路径，即自己明确设置GUID值。  
 所以在每个C ++ / CLI包装器项目的CMakeLists.txt中，我有这样的东西：  
# Set a global cache variable for this project GUID
# The TestAppNet csproj needs this GUID to properly reference this project
set_property(GLOBAL PROPERTY Wrapper_GUID "1897F4D1-E929-444E-9343-00F094113772") 
get_property(projectGUID GLOBAL PROPERTY Wrapper_GUID)
MESSAGE( STATUS "Setting project GUID to: ${projectGUID}")
set(Wrapper_GUID_CMAKE "${projectGUID}" CACHE INTERNAL "Project GUID")
 
 在C＃项目CMakeLists.txt中，我有这个：  
get_property(CMAKE_WRAPPER_GUID GLOBAL PROPERTY Wrapper_GUID)
MESSAGE( STATUS "Setting Wrapper GUID to: ${CMAKE_WRAPPER_GUID}" )
 
 ...然后将CMAKE_WRAPPER_GUID用作在configure_file命令期间填充的.csproj文件中的变量。  
 我不确定这是否有效，但似乎有效！ 

After playing around with this more, I realized what Fraser pointed out - that this method wouldn't always work because I can't expect the GUIDs to be available on a fresh run of CMake. So I went the route that I had seen suggested on the CMake mailing list, which is to explicitly set the GUID values myself. 
So in the CMakeLists.txt for each C++/CLI wrapper project, I have something like this: 
# Set a global cache variable for this project GUID
# The TestAppNet csproj needs this GUID to properly reference this project
set_property(GLOBAL PROPERTY Wrapper_GUID "1897F4D1-E929-444E-9343-00F094113772") 
get_property(projectGUID GLOBAL PROPERTY Wrapper_GUID)
MESSAGE( STATUS "Setting project GUID to: ${projectGUID}")
set(Wrapper_GUID_CMAKE "${projectGUID}" CACHE INTERNAL "Project GUID")
 
And in the C# project CMakeLists.txt, I have this: 
get_property(CMAKE_WRAPPER_GUID GLOBAL PROPERTY Wrapper_GUID)
MESSAGE( STATUS "Setting Wrapper GUID to: ${CMAKE_WRAPPER_GUID}" )
 
... and then the CMAKE_WRAPPER_GUID is used as a variable in the .csproj file that is populated during the configure_file command. 
I'm not sure if this is efficient, but it seems to work!
