Back-end programming

Question

I thought I had idea about back-end. Buh it seems like I know nothing about it. Even though I'm not yet going into it fully , I'll like to know how it is.
After learning a programming language like PHP , what next will be the next step for back-end or server scripting.

Answer 1

If you are writing PHP, you are already doing server side scripting. The ideal next step is to learn how to work with databases.
I suggest you learn MySQL and the use of PDO MySQL(pdo_mysql) driver.
You may further learn how to create a HTTP API. For that you need to learn about REST, cURL extension and object relational mapping. Also learn about PSR 7 and how to use a PSR 7 component like slim/psr7 or nyholm/psr7.
Other areas you might look into are
- Authentication/Authorization
- Model/View/Controller pattern
- Microservice architecture
- Dependency injection and PSR 11
- Unit testing and integration testing.
- Configuring virtual development environments
- Database migration
- Automated deployment
Most of this you can do easily by using a full stack monolithic framework like Laravel.

Answer 2

In addition to above mentioned post I would recommend to install XAMPP server and train all the different possibilitys to handle requests between backend, frontend as well as mysql.
