$this-> is used in what is called a class, which is the build block of OOP (Object Oriented Programming). Basically a class is a set of functions and variables that work together. It allows for easily doing a task without needed to know how it works, just what functions need to be called and (possible in a certain order). This is the idea of OOP, being able to use certain reusable code without needing to know what exactly how a group of functions work together, just what the functions do and do together.

That being said, to explain what $this is. Basically its just a reference to a calling object, the object being a variable in your script that is declared as an object of the class. It is hard to explain more exactly without you having an example of a class infront of you.

Here is a example on php.net

If you need further clarification I can try to explain a little more in depth, but for a really simple answer, its a object variable used in classes
