Hi all,

My system is accessible through an index.php file. This file does a
bunch of includes to include global variables, which in function context
become available through the global keyword:

index.php

<?php
require_once "global_vars.php";

function f() {
global $global_var;
var_dump($global_var);
}

f();

?>

However, apart from access through the index.php file I want to be able
to include my index.php file from a function context:

<?php

function includeIndex() {
require_once ("index.php");
}

?>

The logical result is that variables that are globally accessible to
functions when the system is accessed through index.php are now in the
context of includeIndex() - so they're not global.

I want to fix this problem by not having the include inside of the
function context. How to go upon this?

In index.php rather than declaring vars like so...

$var = 'value';

....declare them in the $GLOBALS array like so...

$GLOBALS['var'] = 'value';

$var is then in the global scope regardless of where it was set.

That would work. However I'm looking for a more generic solution,
independent of the system that is being included. So basically I want to
be able to include a file in my function while stepping out of the
context of the function itself.

I'm not sure what you mean. If you're saying you want to include a file
from inside a function but for all parts of it to behave as if it were
being included at the global scope then I don't believe there's a way to
do it.

Maybe it would be better if you tell us exactly what you're trying to
achieve. I don't really see why my solution above would not work so I
probably don't fully understand what you're trying to do.

put all those variables in a singleton.
then just use MyGlobals::getInstance()->myvar all over the place and you
can do whatever you want with them. of course don't forget to include the
class definition everywhere you want to use it
