PHP for the Web is a terrific introduction on how to use modern PHP effectively. While there is a lot of material out there about building applications with PHP, most of them focus on using a framework like Laravel or Symfony. By working with pure PHP, you will be able to focus on the core ideas instead of how a particular framework implements them.

In this course, you will learn how to use multiple web technologies like POST requests, forms, sessions, and redirects to build a CRUD application with an authentication system.

By the end, you will have all the ingredients at your disposal to go out and build stunning, dynamic PHP web applications.

PHP for the Web: Learn PHP without a Framework

# Solution
Have a look at the complete implementation of the challenge below.

import React from 'react';
import { shallow, configure } from 'enzyme';
import Adapter from 'enzyme-adapter-react-16';

configure({ adapter: new Adapter() });

import HelloWorld from './app';

var TestResult = function() {
    this.succeeded = false;
    this.reason = "";
    this.input = "";
    this.expected_output = "";
    this.actual_output = "";
}

export const executeTests = function() {

  var results = [];

  result = new TestResult();
  result.input = 'HelloWorld Component';
  result.expected_output = "span containing text 'Hello World'"

  let wrapper = shallow(<HelloWorld />);

  // Call your Challenge function here.

  let type = wrapper.type();
  let testSuccessful = true;
  let failureReason;

  if (type !== 'span') {
    testSuccessful = false;
    failureReason = "You need to render exactly one span HTML element";
  } else if (wrapper.props().children != "Hello World") {
     testSuccessful = false;
     failureReason = "You have rendered wrong message in your span element";
  }

  result.actual_output = wrapper.html();

  if (testSuccessful) {
    result.succeeded = true;
    result.reason = "Succeeded"
  } else {
    result.succeeded = false;
    result.reason = failureReason;
  }

  results.push(result);

  return results;
}

# Explanation

Let's break down the solution and analyze it.


## `public/congratulations.php` file

We followed these steps to solve the challenge:
* At **line 3**, we created an array of available languages.
* At **line 10**, we set the default language to English.
* At **line 12**, we declared a variable for the selected language and set it to the default language.
* From **line 14** to **line 20**, we checked if the query parameter `language` or a cookie named `language`  existed and modified the variable of the selected language accordingly.
* From **line 23** to **line 25**, we used the default language if no language was selected.
* At **line 27**, we copied the value of the selected language to a cookie called `language`.
* At **line 29**, we declared an array of messages, as mentioned in the challenge.
* From **line 35** to **line 40**, we added usual  `<html>`, `<head>`, and `<body>` tags.
* At **line 41**, we added an HTML form.
* At **line 44**, we added a `select` element to the form.
* From **line 46** to **line 51**, we added a `selected` attribute to the right `option` element.
* At **line 58**, we added a `submit` button.
* At **line 62**, we echoed a specific message according to the selected language.

Let's solve the challenge given in the previous lesson.
