PHPExcel is a really powerful tool for processing Excel files. I have a report with a pie chart that needs to be converted into Excel. PHPExcel has a relevant example. I referenced and modified it to achieve this effect.
It allows users to generate and download Excel files during the download process, and generate pie charts in Excel.
The example has been modified in two main ways:
1. Change to fetch data from MySQL database
2. Added a solution for Chinese file names to be garbled when downloading under some browsers, such as IE.
The PHP report is as follows:

另要注意的地方是，Excel的饼图，通过指定其标签，值所对应的单元格范围，自动生成，所以主要是在代码中计算好。另在非Windows服务器，生成会失败。
