What kinds of errors are detected during file compilation, prior to PHP execution?

Correct! Wrong!

Explanation:
Syntax errors occur when the PHP parser encounters code that does not conform to the PHP language syntax. Examples of syntax errors include missing semicolons, mismatched parentheses, and misspelled keywords. These errors prevent the code from being compiled into a valid PHP script, and as a result, the script cannot be executed.
When a syntax error occurs, the PHP parser will stop processing the file and report an error message that describes the nature of the error and the line number where the error occurred. This allows the developer to quickly locate and correct the error before attempting to execute the code.

Which of the following commands in Laravel will set a session data?

Correct! Wrong!

Explanation:
The code $request->session()->put('key', 'value'); will set a session data with key and value in Laravel.
The session() method returns an instance of the session manager, which provides several methods for working with session data. The put() method is used to store a value in the session with the specified key.
In the code $request->session()->put('key', 'value');, $request is an instance of the current HTTP request, and the session() method is called on this instance to get the session manager. The put() method is then called on the session manager to store the value with the key in the session.
Once the session data is stored, it can be retrieved in subsequent requests using the get() method, like so: $value = $request->session()->get('key');

The public directory also contains other important files and directories that are accessible to the web server, including the index.php file, which is the entry point for all incoming HTTP requests to the application. The index.php file is responsible for bootstrapping the Laravel framework and handling the request.
