Global Variable not working php

I have a php file tableinfo.php with this code ->

<?php
$table_info = array(
    array(
        'table_name' => 'managers',
        'n_cols' => '4',
        'col_info' => array(
            'Name' => 's',
            'ldap' => 's',
            'avrsid' => 'i',
            'bu' => 's'
        ),
    )
);
?>

I have included this file in another file /controllers/connection.php like this ->

include $_SERVER['DOCUMENT_ROOT'] . '/controllers/tableinfo.php';

connection.php has a class called connection which, in a function uses $GLOBALS to access the array from the tableinfo.php like this ->

$types .= $GLOBALS['table_info'][0]['col_info'][$filters[self::filters][$i][self::field]];

Where $types is a string and $filters is another variable that has the field name that I want.

I autoload the connection.php like this ->

spl_autoload_register(function ($class) {
    require_once($_SERVER['DOCUMENT_ROOT'] . '/controllers/' . $class . '.php');
});

Now, I have two pages, root/js/managers.php and the root/js/ldap.php, on managers.php everything works fine but on the ldap.php it gives this error ->

Notice: Undefined index: table_info in

C:\xampp\htdocs\avrs\htdocs\controllers\connection.php on line 76

I am not able to figure out what am I doing wrong. Please suggest. Thanks in advance.
