I wrote a very simple callback for a Page node I created. The page successfully invokes my callback, but when I put a breakpoint on the one line of code I have in it, notice that there is a variable called $php_errormsg in my list of variables.
Anyone know why I'm getting that variable and what might be causing it?
It doesn't seem to affect the functionality of my callback, but I would like to know what's causing it, if possible.
Thanks in advance
(if the print is too fine on the screen dump, the value of $php_errormsg is "Undefined variable: this". As you can see in my callback, I'm not referring to any variable named 'this')
