Question

我正在学习php，现在它已经被错误阻止了两天＆＃34;解析错误：语法错误，第90行的意外文件结束＆＃34;。我检查了原因，发现它可能来自一个未关闭的标签{，（，＆＃34;，＆＃39;但是当我确认我发现一切正常时。我已经删除了所有行并逐行编写代码，但最后我发现了同样的错误。在某些时候我认为它来自包含的文件，但它在包含它的其他文件中运行良好。你能帮我找一下错误!!

 $get_topics_res = mysqli_query($mysqli, $get_topics_sql)
 or die(mysqli_error($mysqli));

 //there are no topics, so say so

Answer 1

你的第二个heredoc的结尾在它前面有一个空间。

END_OF_TEXT;

删除空格，以便PHP将其识别为heredoc的结尾。
