Use of undefined constant - assumed ' ' - a blank constant?

Question

The undefined contant error is normally quite helpfull and easy to solve, but I am getting some really weird behavior on both my development and production server (different setups).

My error logs shows tons of errors like this:

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]

For me the system trying to define "blank" as a constant?

Often I can solve the error by following the linenumber where their always will be a PHP close tag like this <?php } ?> and by first removing the two spaces <?php}?> and adding them again I can sometime solve the problem. But new errors keeps popping up.

I use netbeans as IDE.

Any suggestions on this behavior would be very much appreciated

Solution

Thank you for the feedback. By enabling non-printable characters in netbeans (view->non-printable Characters in the menubar) I was able to see the difference.

I copied a "bad" space and a curly bracket and made a search/replace in the total project to solve the problem quickly.

Answer 1

You have a non-breaking space in these lines.
You can ask NetBeans to display it for you.
