<?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(-1);
require_once('conn.php');

spl_autoload_register(function($class) {
    require_once ('Classes/'.$class.'.php');
});

$database = new DB($db);

The problem may be in this line:

require_once('conn.php');

Or this:

require_once ('Classes/'.$class.'.php');

You are calling up another file (s). What does he / she do?

Something that helps to know where the problem is is to put echo with something to start before and after the line where you suspect an error. For example:

require_once('conn.php');
echo 'Teste';

If you print, the error is not there.

Another problem may be related to file encoding. If it is encoded with UTF-8, make sure the "Include Unicode Signature (BOM)" option is not checked. If it is, this can cause problems when using commands such as header , session_start () , etc ... for which there can not be any type of printing before them and the BOM is a mark printed on the generated html).

If after these checks the error is not found, please post the complete content (conn.php file) to help you.
