FREE Laravel MCQ Question and Answers

Question 1

Which command should be used to choose the database?

Accepted Answer

$mysqli->select_db(‘databasename’);

Answer

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 2

The number of parameters that a POST operation provides in the URL must be counted. The proper method is:

Accepted Answer

count($_POST);

Answer

The `$_POST` superglobal array in PHP automatically collects all data submitted via an HTTP POST request. To determine the number of parameters sent in a POST operation, you can simply use the `count()` function on the `$_POST` array. This will return the total number of key-value pairs that were submitted through the form.

Question 3

In Laravel, which of the following creates a controller?

Accepted Answer

php artisan make:controller generate

Answer

In Laravel, the `php artisan make:controller` command is used to generate a new controller class. You provide the desired name for the controller as an argument to this command, for example, `php artisan make:controller UserController`. The option `generate` in the correct answer is a placeholder for the actual controller name you wish to create.

Question 4

Which of the following files does Laravel use to set up database connections?

Accepted Answer

.ENV file

Answer

Laravel primarily uses the `.env` file for environment-specific configuration, which includes sensitive details like database connection settings. This file stores critical information such as the database host, username, password, and database name. These values are then loaded into the application's configuration, allowing for flexible and secure management of environment settings.

Question 5

Which of the subsequent parameters is not a factor in file uploads?

Accepted Answer

max_input_time

Answer

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).
