Basic PHP and Symfony 2.8 interview

Dear candidate, please follow this readme and solve all questions.

Before you can start, you should prepare your development environment.

Using Symfony with Homestead/Vagrant

In order to develop a Symfony application, you might want to use a virtual development environment instead of the built-in server or WAMP/LAMP. Homestead is an easy-to-use Vagrant box to get a virtual environment up and running quickly.

Before you can use Homestead, you need to install and configure Vagrant and Homestead as explained in the Homestead documentation.

Resources:

• Using Symfony with Homestead/Vagrant
• Homestead documentation

This test requires:

• access to the internet
• php capable IDE (we suggest PhpStorm with symfony, yaml, twig and php annotations plugin)
• working setup of PHP 5.6 (http://symfony.com/doc/current/reference/requirements.html)
• Doctrine ODM is not compatible with PHP 7.0
• composer (https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx)
• mongoDB (https://docs.mongodb.com/manual/installation/)
• nginx or alternative simple web server

Tip: Install Robomongo on your OS

Tip: Clone the test repository and make sure it's working. Access the project with your favourite browser. You should see similar welcome screen. Dont forget to run composer install.

Help: PHP 5.6+ (debian/ubuntu)

sudo apt-get install -qq php5-cli php5-fpm php5-mysqlnd php5-curl php5-gd php5-json php5-redis php5-imap php5-intl php5-imagick php5-mcrypt php5-xdebug php5-xmlrpc php5-xsl php5-twig php5-mongo php5-dev

Help: (optional) PECL MongoDB library (debian/ubuntu)

sudo apt-get install pkg-config libssl-dev && sudo pecl update-channels && sudo pecl install mongodb

Good luck!

Before you start

• usage of Guzzle is allowed
• you can extend composer.json / add own libraries
• try to follow SOLID and DRY concepts

Test tasks:

1. Create a new Bundle "NasaBundle" within the namespace "Neo"

2. Create a default controller with a method helloAction

• under Nasa namespace
• for route /
• with a proper json return {"hello":"world!"}

1. Use the api.nasa.gov

• the API-KEY is N7LkblDsc5aen05FJqBQ8wU4qSdmsftwJagVK7UD
• documentation: https://api.nasa.gov/neo/?api_key=N7LkblDsc5aen05FJqBQ8wU4qSdmsftwJagVK7UD

1. Write a command

• to request the data from the last 3 days from nasa api
• response contains count of NEOs
• persist the values in your DB (mongoDB)
• Define the document as follows:
  • date
  • reference (neo_reference_id)
  • name
  • speed (kilometers_per_hour)
  • is hazardous (is_potentially_hazardous_asteroid)

1. Create a route /neo/hazardous

• display all DB documents which contain potentially hazardous asteroids
• format JSON

1. Create a route /neo/fastest

• display a DB document data with the fastest asteroid
• format JSON

1. Test your application

Bonus tasks

1. Consider the following code

$str1 = 'foobardoo';
$str2 = 'foo';
if (strpos($str1, $str2)) {
    echo "\"" . $str1 . "\" contains \"" . $str2 . "\"";
} else {
    echo "\"" . $str1 . "\" does not contain \"" . $str2 . "\"";
}

The output will be:

"foobardoo" does not contain "foo"

Why? How can this code be fixed to work correctly?

Save your solution under bonusTasksSolutions.php

1. How many elements contains the $_POST data after executing this request and why?

// JavaScript, jQuery
$.ajax({
    url: 'http://my.site/some/path',
    method: 'post',
    data: JSON.stringify({a: 'a', b: 'b'}),
    contentType: 'application/json'
});

Save your solution under bonusTasksSolutions.php

1. Solve the statement. Write down your solution.

A bread with butter cost 1.10 €. The bread is 1€ more expensive then the butter. How much does the butter cost?

Save your solution under bonusTasksSolutions.php

1. Go to app/config/config.yml and add the following yaml structure. (NOTICE: ping is a child-key of test)

test:
  ping: pong

1. write a command called test:command which accepts 1 argument id

• The command should check if a document with an id of the argument exists
• if document exists, return info "document exists"
• if document doesn't exist, return error "document doesn't exist"
• Add a propmpt for your command. Prompt text is "This is a test. Do you want to continue (y/N) ?"
• If you decline, return error "Nothing done. Exiting..."
• If you accept, run the command

That's it!
