Getting Started with Symfony 4.x
There has been a lot of changes made for Symfony 4, seems to be ok though. I was quite confused, mainly the file structure of Symfony 3 is what I was used to. Then I discovered a nice and quick tutorial with the title Beginners Symfony 4 Tutorial.
The file structure has change if you are developing a web application. There are many, many changes that I may not catch as we move through this.
Step 1 – Symfony Website Skeleton
I am not going to detail this part, if you need that go to the link above.

Please review, edit and commit them: these files are yours. What's next? * Run your application: 1. Change to the project directory 2. Create your code repository with the git init command 3. Run composer require server --dev to install the development web server, or configure another supported web server https://symfony.com/doc/current/setup/web_server_configuration.html * Read the documentation at https://symfony.com/doc Database Configuration * Modify your DATABASE_URL config in .env * Configure the driver (mysql) and server_version (5.7) in config/packages/doctrine.yaml How to test? * Write test cases in the tests/ folder * Run php bin/phpunit |
Step 2 – Change into your new directory:
|
1 2 |
teddy@teddy:~/Documents/works/symfony4$ cd symfony4-blog/ teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ |
Step 3 – Install the Symfony Web Server Bundle: (NO NEED)
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ composer require server --dev Cannot create cache directory /home/teddy/.composer/cache/repo/https---flex.symfony.com/, or directory is not writable. Proceeding without cache Restricting packages listed in "symfony/symfony" to "4.2.*" ./composer.json has been updated Cannot create cache directory /home/teddy/.composer/cache/repo/https---flex.symfony.com/, or directory is not writable.

Step 4 – Now let’s fire up the web server
|
1 2 3 4 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console server:start [OK] Server listening on http://127.0.0.1:8000 |
OR CAN USE PHP SERVER CLI : php bin/console server:run
|
1 2 3 4 5 6 7 8 9 10 11 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console server:run [OK] Server listening on http://127.0.0.1:8000 // Quit the server with CONTROL-C. PHP 7.2.14-1+ubuntu16.04.1+deb.sury.org+1 Development Server started at Thu Feb 7 10:00:54 2019 Listening on http://127.0.0.1:8000 Document root is /home/teddy/Documents/works/symfony4/symfony4-blog/public Press Ctrl-C to quit. |
That command will start the server and this one will stop it.
|
1 2 3 4 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console server:stop [OK] Stopped the web server. |
Note: You do not need to have any other server running. It may cause problems.
Create an .htaccess file (FOR APACHE WEBSERVER)
Mein is like this. Test it out and see if it works for you.
Now COPY & PASTE the following:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 |
# Enable rewrite engine and route requests to framework RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/robots.txt RewriteRule ^(.*)$ /public/robots.txt [L] # resources RewriteCond %{REQUEST_URI} ^/images/ [OR] RewriteCond %{REQUEST_URI} ^/js/ [OR] RewriteCond %{REQUEST_URI} ^/fonts/ [OR] RewriteCond %{REQUEST_URI} ^/css/ RewriteRule ^(.*)$ /public/$1 [L] RewriteCond %{REQUEST_URI} !^/public/ RewriteRule ^(.*)$ /public/$1 [QSA,L] |
Setup the DB (MySql)
Inside the .env file (probably hidden) find this line
|
1 |
DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name |
replace ‘db_user’, ‘db_password’ and ‘db_name’ according to your database credential.
SORRY, ONLY ADMIN CAN SHOW THIS!
Once that’s done, we need to do this (make sure you have the correct db info added first):
|
1 2 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console doctrine:database:create Created database `sf4_blog` for connection named default |
If you already have the database, it’d show this error:
|
1 2 3 4 5 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console doctrine:database:create Could not create database `sf4_blog` for connection named default An exception occurred while executing 'CREATE DATABASE `sf4_blog`': SQLSTATE[HY000]: General error: 1007 Can't create database 'sf4_blog'; database exists |
Auto Versioning setup
Get the auto versioning setup first.
NOTE: This has changed and is easier to install thanks to Flex.

The version is automatically updated with Composer and available in your application.
|
1 2 3 4 5 |
# PHP getenv('SHIVAS_APP_VERSION') # Twig {{ shivas_app_version }} |
Console commands
There are two available console commands. The app:version:bump command is automatically called by Composer on every install and update.
|
1 2 3 4 5 |
# This will display all available version providers bin/console app:version:list-providers # Display a dry run of a version bump bin/console app:version:bump -d |
Go ahead and test those two commands and see what it outputs.

Create an Advanced Blog with Symfony 4 – part3 (FrontController)
Last Updated On March 28, 2018
Introduction
This part of the tutorial will concentrate on getting a basic Homepage/Frontpage structure setup. I opted for a typical blog look.
We will remove files and folders as well add new ones. The Controller for the homepage will be created and the basic page should be viewable at the end.
Get Twitter Bootstrap Layout
I want to have a different look this time, so we will be using some premade templates from the Startbootstrap website. The one we want is released with an MIT license.
First create the PageController
It is easy to do with Symfony 4.
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
teddy@teddy:~/Documents/works/symfony4/symfony4-blog$ php bin/console make:controller Choose a name for your controller class (e.g. VictoriousPuppyController): > PageController created: src/Controller/PageController.php created: templates/page/index.html.twig Success! Next: Open your new controller class and add some pages! |
Let’s see what got created for us. We have a PageController.php file in our src/Controllers folder and inside of the templates folder we have a new folder and a new file, page/index.html.twig
Now that was all I discovered. Run the server: php bin/console s:r
then open the page on http://localhost:8000/page
