<!DOCTYPE html>
<html lang="en-US">
<head>
    <title>Cancel Selection</title>
    <meta charset="utf-8">
</head>
<body>
<h1>College Internship</h1>
<h2>cancel Selection</h2>

<?php echo $Body; ?>
</body>
</html>

它一直说，“解析错误：语法错误，意外T_ENCAPSED_AND_WHITESPACE，期望第42行////CancelSelection.php中的T_STRING或T_VARIABLE或T_NUM_STRING”

我已经完成了五次作业，看不到任何遗漏或错误的内容。有人可以告诉我代码有什么问题或直接指出我如何解决这样的问题？谢谢！
