"Hello World!" doesn't appear

I would also like an answer to this. Worked fine earlier. Closed workspace and reopend and it no longer displays 'Hello World!'. Nothing has changed.

I found deleting the app.txt file also worked for me, that must be the fix!

Deleting app.txt has worked for me as well. Also, when I restarted my browser, app.txt reappeared in the Workspace. The modified warnings now appear with "Oh Noes."

I was having the same issue as everyone else. I am not to positive why its happening but I found this snippet of code and this works for me.

require_once 'vendor/autoload.php';

use Monolog\Logger;
use Monolog\Handler\BrowserConsoleHandler;

$log = new Logger('name');
$log->pushHandler(new BrowserConsoleHandler);

$data = array(1,2,3,4);

// add records to the log
$log->addWarning('Foo');

That's weird! I wonder if this is a composer thing.. It could be that Workspaces isn't storing your installed dependencies - I'm just talking out loud. If that is the problem, you could try running composer install / update.

If that's not the problem, you're code looks fine to me and has been tested by Jason Wist, so it might be worth raising with Treehouse support :)

I'm having the same issue! Everything was fine until I added my namespacing. I did the same as Jason Wist by simply creating a new index.php file and it seemed to do the job. Very odd!

It also means I can't carry on with the next part, as it relies on that functioning.

did you drag your index.php file outside of the vendor folder? It's more of IT problem. LOLs. Location of files do matter in programming and typing where the file is... It's like making nothing appear. So programming is magic. LOLs.

If that was the case Jason, it wouldn't have worked before.

I've tried: Renaming the php file, clearing the cache, restarting the browser, refreshing the file tree inside of workspace and deleting app.txt... so far nothing has worked and i still receive a 500 error. Any help would be appreciated.

Here is my code:

<?php
require "vendor/autoload.php";

  date_default_timezone_set("America/NewYork");

  use Monolog\Logger;
  use Monolog\Handler\StreamHandler;

  $log = new Logger('name');
  $log->pushHandler(new StreamHandler('app.txt', Logger::WARNING));

  $log->addWarning('Warning!');

  echo "Hello World!";

Also, after deleting 'app.txt' and remaking the file my code isn't logging the warnings anymore.

If you have this issue again, type:

"chmod 777 app.txt" (without quotes) into console and try again.

If you haven't even got an app.txt file, create it, then run the above.

For whatever reason, my code will run when I am not using any namespacing on line 12, (assuming you followed the video directly)

Yep, Deleting app.txt worked. Was having same issue.

At first, I got this error message (feel free to skip it): Fatal error: Uncaught exception 'UnexpectedValueException' with message 'The stream or file "app.txt" could not be opened: failed to open stream: Permission denied' in /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:87 Stack trace: #0 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/AbstractProcessingHandler.php(37): Monolog\Handler\StreamHandler->write(Array) #1 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Logger.php(289): Monolog\Handler\AbstractProcessingHandler->handle(Array) #2 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Logger.php(341): Monolog\Logger->addRecord(300, 'Foo', Array) #3 /home/treehouse/workspace/index.php(11): Monolog\Logger->addWarning('Foo') #4 {main} thrown in /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php on line 87 Then I deleted app.txt and everything went fine. The new app.txt has been created, with a correct log.
