FREE Laravel MCQ Question and Answers
In Laravel, which of the following creates a controller?
Explanation:
php artisan make:controller is a Laravel command that generates a new controller class. When you run this command, you specify the name of the controller that you want to create, and Laravel will generate a new PHP file for you with the specified name and a basic template for a controller class.
For example, if you run php artisan make:controller MyController, Laravel will generate a new file called MyController.php in the app/Http/Controllers directory of your Laravel application. This file will contain a basic template for a controller class, which you can then customize to implement the functionality you need.
Which of the subsequent parameters is not a factor in file uploads?
Explanation:
max_input_time is a PHP configuration setting that determines the maximum amount of time that PHP will spend parsing incoming requests. Specifically, it sets the maximum number of seconds that PHP will spend reading and processing input data, such as form data and file uploads, for each request. If the limit is exceeded, PHP will terminate the script and throw a warning.
This setting can be important for applications that involve large file uploads, as it affects how long the server will spend processing an upload request before timing out. By default, the value of max_input_time is set to 60 seconds, but it can be adjusted in the PHP configuration file (php.ini) or using the ini_set() function in PHP code. In Laravel, the max_input_time setting can be configured in the .htaccess file or in the server configuration file.
The number of parameters that a POST operation provides in the URL must be counted. The proper method is:
Explanation:
count($_POST) is a PHP function that counts the number of elements in the $_POST superglobal array. The $_POST array contains data that has been submitted to the server via an HTTP POST request, typically from an HTML form.
The count() function returns the number of elements in an array, so count($_POST) will return an integer representing the number of form fields that were submitted in the POST request. This can be useful for checking if any data was submitted and for looping through the form fields to process them.
Which command should be used to choose the database?
Explanation:
The $mysqli->select_db() method is used to select a database in PHP with the MySQLi extension, which is not directly related to Laravel. Laravel provides its own query builder and Eloquent ORM, which abstract the database layer and provide a more convenient and expressive way to work with databases.
In Laravel, to connect to a database and select it, you typically define the database connection details in the .env file and the config/database.php configuration file, and then use the DB facade or the query builder to interact with the database.
