Prerequisites

To be able to develop comfortably in Symfony we must prepare Windows. For this purpose, it is necessary to install the following components.

• PHP version 7.1.3 or higher. If you want to know how to install it, please check this post.
• You must also have Composer installed. Click here to see how to install it.
• You also need Git. If you want simple instructions on how to install it, please check here.
• Finally, to start programming in Symfony you need a good Integrated Development Environment (IDE). There are many options, however, I show you how to install Visual Code Studio.

Enable the PHP-curl extension.

Symfony requires the php-curl extension to work. Most likely the extension is available, but it is disabled in the php.ini file. If so, just remove the; in the extension, as explained here.

Download Symfony.

The first thing you have to do is go to the official website of the program and download the latest version (5.0.2 at the time of publication).

Then run the file to start the installation. First, select an installation directory.

Then assign the shortcut to the start menu folder.

Then, the assistant adds the program to the environment variable PATH. This is very useful, as it allows you to run Symfony from any console.

Then check the installation options and press Install to begin the process.

Forthwith, the wizard will start downloading the files needed to complete the installation.

Please wait a few moments until the assistant has finished his work.

Configuring Symfony

In the first place, checks if the system meets all the requirements for running Symfony With that in mind, please open the Git Bash and enter the following command:

 symfony check:requirements 

In this case, you can see that the system meets the requirements for running Symfony. Additionally, it offers a number of suggestions to improve the performance of the program

Creating a project with Symfony

There are two options for creating a new project in Symfony. First, you can build a traditional web application. To do so, run the following command:

 symfony new my_project_name --full 

Secondly, there is the option to build a microservice, a console application or API. With that in mind, run the following command:

 symfony new my_project_name 

The only difference between the two commands is the number of required dependencies that are downloaded. In fact, with the FULL variable, all the packages needed to build web applications are installed. Consequently, the installation is larger.

During the process, you have to authorize the access of the program through the Windows firewall.

Testing the project in Symfony.

To be able to run the project, it is necessary to navigate to the installation directory. And then start the server:

cd my-project 
symfony server:start 

Then enter the following in the navigation bar of the browser: http://localhost:8000. If everything has been correct, then you will see Symfony’s initial message.

Conclusion

Ultimately, we have seen how to install Symfony on Windows 10. It can be used as a global application to make any page. In addition, with its template engine, a complete page can be made. It is also widely used to make APIs, which is currently under development. All right, that’s it for now. I hope you’ve learned how to install this wonderful framework. See you later!

PHP is very known. This web-oriented language is widely known for its ease of learning and its power. Fortunately, PHP development is quite active and from time to time we have a new version that helps to improve the stability and security of the applications made with the language. Then, it is convenient to develop with recent versions of the language. Or in the case of servers, it is convenient to have updated libraries and languages so that new applications can run correctly.

Well, let’s get started.

Install PHP 7.3 on CentOS 8

First of all, I always recommend updating the operating system completely, before performing any operation on it.

Open a terminal and run:

:~$ su
:~# dnf update

Now you will have a more secure system thanks to the security patches installed during the upgrade.

PHP 7.3 is available thanks to the REMI repository. The problem is that this repository depends on the EPEL repository. This repository must be enabled.

To enable the EPEL repository, just execute the following command:

:~$ rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm

Once the corresponding package is installed, the EPEL repository will be activated. It’s that simple.

Then, we can enable the REMI repository which is where PHP 7.3 is. To do this, just use this command:

:~$ dnf install https://rpms.remirepo.net/enterprise/remi-release-8.rpm

REMI is a fantastic repository because it has several versions of PHP available. In this case, we are interested in version 7.3. To enable this “section” of the repository, use the following command:

:~$ dnf module enable php:remi-7.3

Now, you can install PHP 7.3 with the following command:

:~$ dnf install php php-cli php-common

This command will install the most basic language as the interpreter. Remember that if you are going to develop or serve applications you have to install the necessary PHP modules.

Finally, you can verify the installed version with the following command:

:~$ php -v

And ready, you can continue installing the PHP modules you need. And start working.

Conclusion

Installing PHP is not complicated in almost any current Linux distribution, however, it is convenient to have recent versions that help improve the fluidity of the system. For this, we use an external repository to provide the packages that by default the distribution does not give us. Today you have learned to install PHP 7.3 in CentOS in a fast and simple way.
