我正在尝试使用下面的表单将4个图像提交到MySQL数据库。当我点击“上传图片”按钮时，会出现错误syntax error, unexpected $end in ...postsubmit.php on line 235。 235行没有任何内容;它只是postsubmit.php的最后一行。知道我为什么会收到这个错误吗？
提前致谢，
约翰
表格：
echo '<form method="post" action="postsubmit.php" enctype="multipart/form-data">

通常，该错误来自PHP解析器，在找到预期语法之前到达脚本末尾。很可能是一个未闭合的大括号}。
答案 1 :(得分：1)
在文件的最后添加一个右括号}。
您从未关闭assertValidUpload()功能。
另外，您的代码样式不一致（可能只是此站点上的格式）：
在assertValidUpload()函数的开头，您将左括号放在下一行，您应该将它移动到与函数定义声明相同的行。这些事情有助于你的代码中的不一致性 - 从而帮助你发现这样的错误。
