Summary
In this chapter, we have taken a look at a few new features that are available with PHP 5.4 and PHP 5.5. We have also looked at unit testing, and how it could help us streamline our software development life cycle by testing individual units of our application by using PHPUnit's test cases. The last topic that we have discussed is establishing a connection with our MariaDB database. In the next chapter, we will begin by discussing how HTML interacts with PHP and move forward with building our student portal application.
