未定义的内容错误通常非常有用并且易于解决，但我在开发和生产服务器（不同的设置）上得到了一些非常奇怪的行为。
我的错误日志显示了大量错误：
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”定义为常量？
通常我可以通过跟随整个错误来解决错误，其中它们总是像这样<?php } ?>的PHP关闭标记，并且首先删除两个空格<?php}?>并再次添加它我有时可以解决问题。但是新的错误不断涌现。
我使用netbeans作为IDE。

非常感谢有关此行为的任何建议
感谢您的反馈。通过在netbeans中启用不可打印的字符（菜单栏中的view-＆gt;不可打印的字符），我能够看到差异。
我复制了一个“坏”空间和一个大括号，并在整个项目中进行了搜索/替换，以便快速解决问题。
