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.
