[Resolved] global doesn't want to walk through the door...?

vaaaska

I don't know if I'm just being stuipd of what...but I can't get this global to come inside the function...

//print_r($error_msg); exit;

function Pagina()
{
    global $error_msg;
    print_r($error_msg); exit;

If I uncomment the first print_r it will print out the error arrays...

Now, when I turn off the first print_r and let things run into the function I can't access the error arrays. Hopefully, this is enough of an example...but it's all I'm toying with. The arrays do exist (outside of the function) and I'm not sure what I could possibly be doing wrong.

Is there something simple I'm forgetting about here?

Thanks...v

Not like I know what I'm doing, but there are a couple of hints on the print_r page about how the function works. I'm thinking of the return parameter -- print_r($error_msg,TRUE), and also the fact that it may be necessary to reset($error_msg). I have been using the return parameter a lot as it generally provides more output control. i.e. return(print_r($error_msg,TRUE)); print_r()

I'm not completely sure why (and I'm sure somebody will pop up and inform me of my incompetence soon)...

But David's post gave me an idea to use:

$GLOBALS(error_msg) = $error_msg;

And it works...

Merci beacoup...v
