未定义的持续错误通常很有帮助且易于解决，但是我的开发和生产服务器（不同的设置）都出现了一些非常奇怪的行为。
我的错误日志显示了大量这样的错误：
NOTICE (5): [8] Use of undefined constant - assumed ' ' (#PATH#/dashboard/tasks.tpl) [61]
NOTICE (5): [8] Use of undefined constant - assumed ' ' (#PATH#/index/view.tpl) [158]
NOTICE (5): [8] Use of undefined constant - assumed ' ' (#PATH#/blogs/index.tpl) [51]
对我来说，系统试图将“空白”定义为常数？
通常我可以通过跟踪行号来解决错误，其中它们总是像这样的 PHP 关闭标记，<?php } ?>并且首先删除两个空格<?php}?>并再次添加它们，有时我可以解决问题。但是新的错误不断出现。
我使用 netbeans 作为 IDE。

对此行为的任何建议将不胜感激
解决方案
感谢您的反馈。通过在 netbeans 中启用不可打印字符（菜单栏中的视图-> 不可打印字符），我能够看到差异。
我复制了一个“坏”的空格和一个大括号，并在整个项目中进行了搜索/替换，以快速解决问题。
