PHP Operators

PHP operators are characters (or sets of characters) that perform a special operation within the PHP code. For example, when you use the equals sign ( = ) to assign a value to a variable, you are using an assignment operator. When you add two numbers together using a plus sign ( + ), you are using an arithmetic operator.
