Introduction to User Authentication in PHP
Do you want users to be able to interact with your site? Do you want users who are active participants in the content you provide? That interaction could be purchasing products or adding products to sell, leaving comments or providing blog posts. No matter which type of interaction your site provides to users, you'll need a way to authenticate those users. In this course we'll lay the foundation for keep your data safe and secure while building a platform for active participation.
Continuous Integration with Jenkins
Jenkins is a continuous integration server. Integration tests take all the code and other components of your application and integrate it together, then test it to ensure it's working properly. Jenkins can watch repos for version control software like Git or Subversion. When there's a new commit, Jenkins will check it out automatically. It will run your tests, and report the result. It can even be configured to automatically deploy your software to production if all the tests pass. This course is going to show you all the basics of using Jenkins.
Introduction to Regular Expressions
Regular Expressions are like having a secret code for telling a computer exactly what you want. Regex, as it's often referred to, is a text string for describing a search pattern. You can think of it as a supercharged version of a find tool. In this course, we'll explore what regular expressions are, and get some practice using them.
