The Back-end development is the hidden part of a web or mobile application. It concerns the part of the code that runs on the server side.

Back-end developers create services that manage the business logic and access resources such as databases, file servers or Cloud services. 

In this respect, we are going to look at two famous backend technologies: PHP and MySQL.

​

1 - Php:

 

• PHP is a server-side programming language.

• Mainly used to create dynamic web pages.

• Used to interact with databases, generate dynamic content and manage user sessions.

• Often used in combination with MySQL to create complete web applications.

​

2 - MySql:

 

• MySQL is a relational database management system (RDBMS).

• It stores and manages data in tables.

• Often used as a database for web applications.

• works perfectly with PHP.

In short, back-end development with PHP and MySQL makes it possible to create robust, secure and high-performance web applications.
