DevOps enables organizations to deliver applications to their users with agility. Continuous integration and continuous delivery (CI/CD) pipelines are an important component of DevOps. They automate the processes for developing and deploying applications automatically. 

In this course, you will take a project-based approach to learning about some of the most popular CI/CD pipelines. You will start by learning how to create a PHP application using the Symfony framework, and add some features to the skeletal code. Then, you’ll learn to deploy it to AWS Elastic Beanstalk. Next, you will learn to automate the build and deployment steps using GitHub Actions, Bitbucket, GitLab, and AWS CI/CD pipelines.

At the end of the course, you will have knowledge of working with some of the most popular CI/CD pipelines. You’ll know the best practices of working with authentication secrets for each of these pipelines and be able to deploy any web application to AWS Elastic Beanstalk using any of these CI/CD pipelines.

Mastering Web Application Deployment Using CI/CD Pipelines

In this lesson, we'll create a PHP function and make our new web page use it. This function will be used for PHPUnit testing later on in the course.

# Add a PHP function

First, let's create a simple testable PHP function. 

- In the widget below, find the `src/Controller/NewPageController.php` file.
- Add the new function. 
```
    public function personalMessage(): string
    {
        return "PHP is cool";
    }
```

# Modify the `index()` function

Now, let's call our new `personalMessage()` function so we can see the result in our `/new_page`.

- In the widget below, find the `src/Controller/NewPageController.php` file.
- Modify **line 15** of the `index()` function to the code below: 
    - This code calls our new `personalMessage()` function.
```
            '<html>
                <body>
                    Hello welcome to new page.
                    <br>
                    '.$this->personalMessage().'
                </body>
            </html>'
```

Our whole `NewPageController.php` PHP file code should look like this:
```
<?php

namespace App\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;

class NewPageController extends AbstractController
{
    #[Route('/new_page', name: 'new_page')]
    public function index(): Response
    {
        return new Response(
            '<html>
                <body>
                    Hello welcome to new page.
                    <br>
                    '.$this->personalMessage().'
                </body>
            </html>'
        );
    }

    public function personalMessage(): string
    {
        return "PHP is cool";
    }
}
```

# Run and test the app

- Click the "Run" button and wait for the application to be built.
- Click the URL under the “Run” button to open the application in a new tab, `https://XXXXXXX.educative.run/new_page`.

There should be a page returning:
```
Hello welcome to new page
PHP is cool
```

# Summary

We created a new function named `personalMessage()`, which returns a string message. This function is then called from the `index()` function, which displays the `PHP is cool` message on the new web page.

Well done on creating PHP functions! We can now move on to making PHPUnit tests.

Learn how to create a PHP function to run a unit test.
