syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING
提问by user1083482
I have been staring at this code for hours now and I cannot figure out where my mistake is. I know this syntax error usually comes up because of some missing or out of place curly brace or some issue with single/double quotes and I'm not sure there is one anywhere in my code. I am only trying to fix my syntax right now so I can get the code to completely compile. Any help would be much appreciated. Here is my code:
我已经盯着这个代码几个小时了，我不知道我的错误在哪里。我知道这个语法错误通常是由于缺少或不合适的大括号或单/双引号的一些问题而出现的，我不确定我的代码中是否有任何地方。我现在只是想修复我的语法，这样我就可以让代码完全编译。任何帮助将非常感激。这是我的代码：

I stumbled on this question as I had the same error. Mine was due to a slightly different problem and since I resolved it on my own I thought it useful to share here. Original code with issue:
我偶然发现了这个问题，因为我有同样的错误。我是由于一个稍微不同的问题，因为我自己解决了它，所以我认为在这里分享很有用。有问题的原始代码：
$comment = "$_POST['comment']";
Because of the enclosing double-quotes, the index is not dereferenced properly leading to the assignment error. In my case I chose to fix it like this:
由于包含双引号，索引未正确解除引用导致分配错误。在我的情况下，我选择这样修复它：
$comment = "$_POST[comment]";
but dropping either pair of quotes works; it's a matter of style I suppose :)
但是删除任何一对引号都有效；我想这是一个风格问题:)

Your problem is that you're not closing your HEREDOC correctly. The line containing END;must not contain any whitespace afterwards.
您的问题是您没有正确关闭 HEREDOC。包含的行END;之后不得包含任何空格。
回答by Toto
You have extra spaces after END;that cause the heredoc not terminated.
之后您有额外的空格END;，导致heredoc 未终止。

Might be a pasting problem, but as far as I can see from your code, you're missing the single quotes around the HTML part you're echo-ing.
可能是粘贴问题，但就我从您的代码中看到的而言，您缺少回显的 HTML 部分周围的单引号。
If not, could you post the code correctly and tell us what line is causing the error?
如果没有，您能否正确发布代码并告诉我们哪一行导致错误？
