【问题描述】：
我一直在做一个网站，我们被要求加入 php，并使用页眉/页脚。我的工作没有错误，除了“未完成错误的头部结束标签”我已经将头部的结束标签移动到整个地方并且无法弄清楚为什么它仍然会抛出错误。验证时如何解决这个愚蠢的错误

【问题讨论】：
-
是什么给了你这个错误？你在哪里看到的？
-
它在 w3 验证器中显示第 11 列第 7 行
-
PHP解析完后能显示源码吗？
-
“我的工作没有错误” + “无法弄清楚为什么它仍然会抛出错误” - 你在自相矛盾。另外，
<?php $title ?>应该做什么？这只是一个处于不确定状态的变量。你的文件是.php，对吧？ -
渲染时 php var $title 会产生什么？
