max_input_time (Correct answer)
max_execution_time
max_file_size
post_max_size

Correct answer: max_input_time

While `max_input_time` limits the time a script spends parsing request data, it is not a direct factor in the *size* or *execution* of a file upload itself. The primary PHP configuration directives that directly influence file uploads are `upload_max_filesize` (maximum size of an individual uploaded file), `post_max_size` (maximum size of all POST data, including files), and `max_execution_time` (maximum time a script is allowed to run).

Question 21: Which config file defines the default authentication guard and user provider in Laravel?

config/auth.php (Correct answer)
config/security.php
config/session.php
config/app.php

Correct answer: config/auth.php

Double curly braces {{ $var }} automatically escape HTML entities to prevent XSS attacks.

Question 27: Which of the following files does Laravel use for interpolation?

[]
[]
None of the above
{{}} (Correct answer)

Correct answer: {{}}

Laravel's Blade templating engine utilizes the double curly brace syntax, `{{ expression }}`, for displaying the contents of a variable or the result of an expression. This syntax automatically escapes the output to prevent Cross-Site Scripting (XSS) attacks, making it a secure way to interpolate data into your views. For unescaped output, `{{{ expression }}}` or `{!! expression !!}` can be used.

Question 28: Which professional practice should be followed when writing Laravel migrations to ensure they are safely reversible?

Always drop and recreate tables in `down()`
Only implement the `up()` method
Implement both `up()` and `down()` methods correctly (Correct answer)
Use raw SQL in both methods without Schema builder

mysqli->select_db(‘databasename’);
$mysqli->select_db(‘databasename’); (Correct answer)

Correct answer: $mysqli->select_db(‘databasename’);

When using the `mysqli` object-oriented interface in PHP, the `select_db()` method is the correct way to choose the default database for subsequent queries. This method is called on an existing `mysqli` connection object, with the desired database name passed as an argument. It ensures that all subsequent SQL operations are directed to the specified database.

Question 31: In Laravel, where must a newly created middleware be registered to apply it to routes?

routes/web.php
app/Http/Kernel.php (Correct answer)
config/middleware.php
bootstrap/app.php

Correct answer: app/Http/Kernel.php

Middleware must be registered in the `$middleware`, `$middlewareGroups`, or `$routeMiddleware` arrays inside `app/Http/Kernel.php`.

Question 32: What is the difference between the `web` and `api` authentication guards in Laravel?

web routes are encrypted while api routes are plain
web uses OAuth2 and api uses basic auth
web uses session/cookie storage while api uses token-based stateless authentication (Correct answer)
web is for admin users and api is for regular users

Correct answer: web uses session/cookie storage while api uses token-based stateless authentication

The web guard maintains state via session cookies, whereas the api guard is stateless and authenticates each request via a token.
