编辑：
用于下载的my project链接PHP字符串比较区分大小写。由于您有method=“post”
，您将在$\u服务器['REQUEST\u method']
中获得post
，并且post==post
为false
：
php > var_dump('POST' == 'post');
bool(false)
在IF之前，可以尝试回显您的$\u服务器['REQUEST\u METHOD']
变量
或者var\u dump（$\u SERVER）
并检查此数组中的错误-可能您的服务器没有设置请求方法键
或者尝试：
if( count($_POST) ){/*....*/};
if（$\u服务器请求\u方法==post）
← 这是你的密码吗？？请尝试if（$\u服务器['REQUEST\u METHOD']=='POST'）
。我将'POST'改为小写，但不回显结果中的任何内容！！你也加上引号了吗？如果您看到一个空页面，PHP可能会因为解析错误而中止。检查服务器的错误日志，查看其中是否报告了任何错误。另外，添加行错误报告（E_ALL）到PHP脚本的顶部。这是我的项目链接供下载和测试：我测试了它，但没有回应任何内容，所以要进行基本调试：var\u dump（$\u SERVER['REQUEST\u METHOD']）
，看看你真正得到了什么。我在我的问题中添加了结果！我把结果加到问题上
if( count($_POST) ){/*....*/};
