Learn the fundamentals of PHP from structural programming to object-oriented techniques.

Web Development with PHP

This highly interactive module introduces us 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 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 into advanced concepts such as classes, inheritance, and exception handling in PHP. By the time we're done, we’ll have a good grip on the basics of PHP and will be ready to study advanced concepts.

# What are Operators?
An operator is something that takes one or more values (or expressions, in programming jargon) and yields another value (so that the construction itself becomes an expression). For instance, when you add two numbers, say `2` and `5` (**values**) it yields `7` (**value**), such that the construction itself becomes an **expression**, i.e. `2+5=7`.

# Types of Operators
There are multiple types of operators for various purposes, i.e.,

- arithmetic operators
- comparison operators
- logical operators
- assignment operators

The following figure illustrates the various kinds of operators in PHP:
