我错过了一个我找不到的花括号。 解析错误显示在我的代码末尾。我已经花了很长时间。我不太了解如何识别这些错误的PHP提示会有所帮助。

确保正确的括号匹配的一种常用方法是将每个{}的内容缩进一个标签而不是外部。
答案 1 :(得分：0)
您错过了源代码中第54行打开的“尝试”构造的“捕获”。
答案 2 :(得分：0)
将其添加到代码顶部
error_reporting(E_ALL);
但是当您找不到错误时，请开始删除代码段并再次运行文件网页，直到错误消失。
例如从代码中删除include footer.inc.php，删除一些PHP代码以实际查找导致错误的原因。然后，您可以慢慢地添加代码以查看触发错误的内容。

通常，这不是SO的用途，但是......
if($emailaddress == '' || $password == ''){
throw new Exception('E-mail and password must be supplied to login. Please try again.');
}else{
/*VALIDATE FOR DATA*/
这里的“其他”似乎没有匹配的右括号。至少，根据我的文本编辑器，它有支撑匹配。 （值得研究......）
更新：实际上，您似乎缺少2个关闭括号。请参阅下面的重新格式化代码：
（请参阅### THIS BRACE IS UNMATCHED ###标记。）

大多数编辑都能够突出显示匹配的大括号。
关于如何避免这些的提示：代码约定！我不会说究竟要在哪里打算什么，以及{和}是否应该在一个新的行或相同的，但总是以相同的方式。多年来，你会发现这些东西非常快 - 如果正确的话
