Ok, I'm not sure if I understand what you mean. Are you saying that I should
read one php statement at a time and evaluate the php statements?

That is, I might read the file into an object and then parse it one
statement at a time and eval each statement. This way I could step through
the code... not necessarily the best way but does let me debug my code.


The problem is, that in my code I do something like

eval('?>'.AddNavToPage($MainPage));

Where $MainPage is just an html file that acts as a template(I probably
could have included it aftwards instead of the way I did it but I think its
probably to late to recode it at this point).

So when I debug the code I get to this line and then cannot debug whats
inside.

What is inside is what AddNavToPage does, which is inserts a php/html file
$mainpage into the template page to generate the total page.

Essentially AddNavToPage returns a mixed php/html that was stiched together
by 2 other pages.

I suppose I could save it to a temp file like you mentioned and then include
it and it should work?

that is, instead of the eval line I could do

if ($DEBUG)
{
file_put_contents($temp, AddNavToPage($MainPage)));
include $temp;
}

(psuedo code)

I'll try that and see what happens,

Thanks,
Jon
