_README

== About this Gist ==
I can't figure out wtf is going on here.  Something strange with variable scope that I can't quite wrap my mind around.  
If anyone knows the solution, please email me at meltingice@meltingice.net

This is a huge generalization of my code... some of the functions here aren't even a part of my codebase, 
but they will still produce the same result and they are easier to understand because of their simplicity.

Also, I am using either PHP 5.3.0 or PHP 5.2.8 for this code.

== Where to Start ==
The user loads testfile.php in their web browser which includes config.php.  You can probably follow it from there pretty easily.

PHP prints out the error I commented in testfile.php (except, you know, with the filename and line number instead of the class and function).

config.php

<?
include('osimo.php');
$osimo = new Osimo();
?>

db.php

<?
class OsimoDB{
    function OsimoDB(){
        // options stuff
    }
    
    // ...
    // lots of other stuff
    // ...

    /*
     * Not a real function in my class, but serves the same purpose
     */
    public function doQuery($sql){
        get('cache')->sqlquery($sql); //$osimo->cache is not defined/found
    }
}

osimo.php

<?
class Osimo{
    function Osimo(){
        // ...
        // set some options here
        // ...

        $this->init();
    }

    private function init(){
        $this->loadIncludes();
        $this->cache = new OsimoCache();
        $this->db = new OsimoDB();

        $this->loadConfig();
    }

    public static function loadIncludes(){
        include_once('db.php');
        include_once('cache.php');
        // etc...
    }

    private function loadConfig(){
        $this->db->doQuery('sql query'); //assume it knows to check the cache in this generalization
    }
}

function get($class){
    global $osimo;

    if($class=='osimo' && isset($osimo)){
        return $osimo;
    }

    if(is_object($osimo->$class)){
        return $osimo->$class;
    }
}
?>

testfile.php

<?
include('config.php');
// Fatal error: Call to a member function sqlquery() on a non-object in OsimoDB::doQuery()
?>
