php __autoload() is not working - php

Question

I haven't seen any error in my files but when I run my code it shows me the following error:
Warning: require_once(Core.php): failed to open stream: No such file or directory in C:\xampp\htdocs\completed\inc\autoload.php on line 7
Fatal error: require_once(): Failed opening required 'Core.php' (include_path='.;C:\xampp\php\PEAR') in C:\xampp\htdocs\completed\inc\autoload.php on line 7
My code is:
classes/Core.php
<?php
class Core {
public function run() {
ob_start();
require_once(Url::getPage());
ob_get_flush();
}
}
inc/autoload.php
<?php
require_once('config.php');
function __autoload($class_name) {
$class = explode("_", $class_name);
$path = implode("/", $class).".php";
require_once($path);
}
index.php
<?php
require_once('inc/autoload.php');
$core = new Core();
$core->run();

Answer 1

I know it's a bit late. I was researching on this because I had the same problem. This is what i tried and it worked for me.
// this code is for the inc/autoload.php file.
define('__ROOT__', dirname(dirname(__FILE__)));
require_once(dirname(__FILE__) . "/config.php");
//require_once(inc/config.php);
function __autoload($className){
$class = explode("_",$className);
$path = implode("/",$class).".php";
require_once($path);
}
Please I just started learning PHP and i stand corrected by you guys.
I hope this helps.

Your Core class is apparently defined at:
C:\xampp\htdocs\completed\classes\Core.php
But you attempt to load this file:
C:\xampp\htdocs\completed\Core.php
It isn't a good idea to build a class auto-loader that works with relative paths*. I suggest you add a prefix here to build an absolute path:
$path = implode("/", $class).".php";
E.g.:
$path = __DIR__ . '/../classes/' . implode("/", $class).".php";
(*) Among other reasons, because relative paths in PHP are relative to the main script (rather than the file when path usage happens) so the source directory depends on what script you load autoload.php from.

Answer 3

I've faced the same problem with yours. I think it's late for you. But may be it's helpful for others.
I didn't included the config.php file in autoload.php file
inc/autoload.php
//require_once('config.php');
I included config.php file in the index.php like this:
index.php
require_once('inc/config.php');
require_once('inc/autoload.php');
And it's worked fore me, I hope this for you, too :). Thanks for your time to read my comment.

because in same folder
require_once('inc/autoload.php');
require_once('config.php');
so.. i think may be should like this
require_once('inc/config.php');
