您忘记命名提交字段：

                <label for="Name">Name:</label>
                <input type="text" name="name" id="Name" accesskey="N" tabindex="1">

                <label for="Email">E-mail:</label>
                <input type="text" name="email" id="Email" accesskey="E" tabindex="1">

                <label for="Phone">Phone Number:</label>
                <input type="text" name="number" id="Number" tabindex="1">

                <label for="Comment">Comments</label>
                <textarea type="text" name="comment" id="Comment" rows="27" cols="70" tabindex="1"></textarea>

                <input id="mySubmit" type="submit" value="Submit">
            </form>
    </fieldset>
</div>

            <input id="mySubmit" type="submit" value="Submit" name="submit">
                                                              ^^^^^^^^^^^^^

相反。如果执行POST，则始终是这样。正如您在版本中看到的，一个简单的输入错误或疏忽将完全扼杀您的逻辑。
首先清空您的文件，只需放入
标题（“Location:Thanke.html”）在php标记中。如果可行，则逐步添加其他行。你会看到恼人的台词。阅读PHP参考网站上的标题。应该小心地使用它
请
对
if
语句的每一个可能结果都回显
一个响应，然后发布您得到的响应，以准确地找到问题所在。
