Learning a programming language is one thing and using it to build something great is another. I've been teaching code newbies and aspiring developers for a long time and I see many of them struggling to put into practice their newly acquired skills. I've also noticed that many resources on the Internet are out-of-date, misleading, or don't provide real hands-on practice.

I've built this course to fix the issues above. You'll learn a better way to build a modern and production-ready PHP app connected to a database like a pro. The app, a CRUD one, will also have some more advanced features like I/O security, router, and more. 

At the end of this course, you'll be well equipped to build database apps with PHP.

No matter how complex of a client-side validation we perform, server-side validation is just as crucial and important.

Front-end validation can be bypassed if:

> **Curious to know how front-end validation can be bypassed?** 
> - A malicious user turns off JavaScript on their browser.
> - Middlemen attacks occur, which change the data after the request is submitted by a user, but before it is received by the server.


We’ve been practicing back-end validation in the previous lessons. Let’s recall how to conduct some of those validations:

## Prepared statements

In the event  that we need to rely on user inputs to perform database tasks:
