Fatal Error Using namespaces in PHP - Build A Simple Website

This is there error I am getting

Fatal error: Uncaught UnexpectedValueException: 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:97 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(336): Monolog\Handler\AbstractProcessingHandler->handle(Array) #2 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Logger.php(391): Monolog\Logger->addRecord(300, 'Foo', Array) #3 /home/treehouse/workspace/index.php(8): Monolog\Logger->addWarning('Foo') #4 {main} thrown in /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php on line 97

This is the code I am using <?php require DIR . '/vendor/autoload.php'; date_default_timezone_set('America/Los_Angeles');

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

$log->addWarning('Foo'); echo 'Hello World!';

It worked when I created it, once I added namespaces using 'USE' it stopped working. When I reverted back to the original code 'shown above' I got the same error.

It would be better to show the code you are using. If its a Treehouse assignment, attach challenge too.

I found my own solution. Simply delete the app.txt file and it seems to work again. A new app.txt file will be created when you run the program again.

Warning: require(vendor/autoload.php): failed to open stream: No such file or directory in /home/treehouse/workspace/vendor/index.php on line 2

Fatal error: require(): Failed opening required 'vendor/autoload.php' (include_path='.:/usr/share/pear:/usr/share/php') in /home/treehouse/workspace/vendor/index.php on line 2

This is what I am getting too. Please help.

The reason why this happens is because of Linux user permissions. When the file is created at first as in the previous video, the owner of the file (with read and write permissions) is user "treehouse". When using 'use' the executing script is apparently owned by user 'apache' and only has read access to the file. You can either change file permissions or delete the file and recreate it with the new setup.
