This highly interactive course introduces you to fundamental programming concepts in PHP, one of the most popular languages in the world. It begins with a simple Hello world program and proceeds on to cover common concepts such as Conditional Statements, Loop Statements, and Logic in PHP. 

It then reflects upon the idea of Functions and Arrays, as well as the power they give to the programmer to write better code. 

Finally, it dives deeper in order to teach about advanced concepts such as Classes, Inheritance and Exception Handling in PHP. By the time you're done, you'll have a good grip on the basics of PHP, and will be ready to study advanced concepts.

There are only two string operators:
* Concatenation (`.`):
* Concatenation Assignment (`.=`)

## Concatenation
The most important operation in strings is *concatenation*. It means joining one string to another. For instance, the concatenation of `water` and `bottle` will result in a string `waterbottle`.

Run the code below to see how this is done:
