"Fatal error: Class declarations may not be nested" when debugging with Netbeans

[JohnArcher]

Hi there,

first I want to apologize if this not the right place to post this ... :-( I am using KLogger and PSR Log (https://github.com/php-fig/log) together with Symfony's ClassLoader Component (https://github.com/symfony/class-loader) to autoload KLogger and PSR Log.

My test code looks like this:

<?php

require_once __DIR__.'/class-loader/ClassLoader.php';

use Symfony\Component\ClassLoader\ClassLoader;

$loader = new ClassLoader();
$loader->register();

$loader->addPrefix('Psr\\Log', __DIR__);
$loader->addPrefix('Katzgrau\\KLogger', __DIR__);

$users = array(
    array(
        'name' => 'Kenny Katzgrau',
        'username' => 'katzgrau',
    ),
    array(
        'name' => 'Dan Horrigan',
        'username' => 'dhrrgn',
    )
);

$logger = new Katzgrau\KLogger\Logger(__DIR__.'/logs');
$logger->info('Returned a million search results');
$logger->error('Oh dear.');
$logger->debug('Got these users from the Database.', $users);

Everything works fine under this conditions:

1. I do not debug
2. I do debug (Netbeans, XDebug) and step into new Katzgrau\KLogger\Logger()

It does not work, if I set a breakpoint before new Katzgrau\KLogger\Logger() and when the breakpoint is reached I click "Continue (F5)". Then I get this fatal error:
Fatal error: Class declarations may not be nested in path\to\project\Psr\Log\LogLevel.php on line 9

I tried a lot to figure out what is going on. The only workaround I found was uncomment use Psr\Log\LogLevel; in Logger.php and copy the class definition of Psr\Log\Level directly into Logger.php (that's why I am posting it here).
But for obvious reasons I don't want to modify your code this way.

Does anyone know what and why is this happening?

Thanks a lot!

Regards

Yeah, not really a KLogger problem. At least the problem seems limited to debugging and setting a breakpoint at a specific place. It could be a potential issue with xdebug. I would check php's error_log to see if there's anything more specific in there.

Thanks for your answer. Nope, error_log has no more infos.

I have never seen this issue before and done plenty of debug sessions.

Can you tell us your exact setup?
