Hey this is WellExplained and I'm Vladimir Grankin. I have more than 10 years of experience in web development and I have worked for different web companies during these years. I also have a Bachelor's degree in Computer Science.
What is unique about this course is that it gives you an opportunity to become one of the best, most valuable PHP developers on the market! Both absolute PHP beginners and experienced developers will greatly benefit from taking this course. We focus on the fundamentals here. We cover namespaces, operators, types, variables, functions, object oriented programming, constants, expressions, sessions, cookies, exceptions, generators, references, garbage collection and many many more! Hundreds of examples are provided and explained in great detail to make sure you got each and every concept.
We will extensively use official PHP documentation in our course. In fact it is based on PHP manual. And what is the advantage of using PHP manual? The biggest advantage is that this is the best, most genuine source of documentation and quality information on PHP available and it is also maintained by PHP creators. We will go through all covered concepts in great detail, will examine hundreds of examples provided in the PHP manual for covered topics and will add even more examples to make sure you fully understand the concept. And once you understand the concepts behind the code you write, you become a true professional!
After completing this course you will be ready to dive into any PHP project imaginable, because it lays very strong foundation.
This course was made with modularity in mind. Here is what you will learn in each module of the course:
PHP Getting Started - this is a "high altitude" introduction to PHP usage. It answers such questions as what is PHP and what can PHP do. Also a simple PHP tutorial is provided, which will show you how to create your first PHP-enabled page! Great for absolute PHP beginners!
