Variable Scope

[GilesGuthrie]

Does anyone here code using global variables? I'm having real difficulty with them. Like they're not working!

If I do the following:

global $year;
$year = 2003;

function printyear()
{
   echo "From inside the function: ".$year;
}

echo "From outside the function: ".$year;

I get:

From inside the function: 0
From outside the function: 2003

Which isn't good. It's not life threatening, because it just means I have to pass the variable all the time, which is a pain. Am I being dense here?

Has nobody got any ideas?

I don't know PHP - I would help ya out if I knew though.

Uh. I don't know alot about PHP but it looks ok to me. I don't see why it would not work.

Put the global inside the function.

Might fix your prob.

I truely know my way around PHP, it seems.

Oh, right. Thanks for that Cory. I never would have thought to do it that way. Guess my grounding in C is a bit more pervasive than first thought!

Am now retreating back into Programmerville, as am coding PHP that writes Javascript. It's something of a head****!

No problem buddy.
