TP6用word文档导入数学公式
近期需要做word文档导入试题的功能，试题中含有一些复杂的数学公式，导致word文档读取后直接报错。报错以下：
PhpOffice\Math\Reader\OfficeMathML::getElement :
The tag `m:r` has no tag `m:t` defined1、首先去问了下deepseek，给出的回复如下：
您的报错信息 PhpOffice\Math\Reader\OfficeMathML::getElement :
The tag m:rhas no tagm:t defined 表明 PHPOffice 库在解析 Office MathML 格式的数学公式时，
发现某个 <m:r> 标签内部缺少必需的 <m:t> 标签。按照其给出的方案反复修改依旧无法解决报错问题，最终发现是目前 PHPWord 官方版本（ phpoffice/phpword）对包含数学公式（Office MathML/OMML）的 Word 文档（.docx）的读取支持有限。
2、后来偶然发现，word文档其实就是个打包后重命名的压缩包文件，将本地的.docx文件直接重命名为.zip压缩包，解压缩后可以得到以下目录结构的文件包：
图1 主文件夹 图2 子文件夹
图2 子文件夹中的document.xml文件其实就是word文档的含公式内容。实际需要读取的也就是这个xml文件了。
那么，换个思路，准备不直接读取word了，曲线救国换成读取document.xml这个xml文件试试呗。
还别说，真好使。公式乖乖的蹦出来了。
具体代码结构如下：

<!-- 需要在页面头部引入以下js文件 MathJax-master包省略 -->
<script>MathJax = {loader: { load: ["input/mml", "output/svg"] }};
</script>
<script src="js/MathJax-master/tex-mml-svg.js"></script>此处输出含公式的试题内容接口
{$exam_question}至此，word导入的公式就可以完美显示在前台了。如下所示：
报错处理：
