PHP Operators – Arithmetic operator, Assignment Operator, Increment-decrement Operator

## PHP Operators
To work with PHP variables and make any operations, PHP operators are used. Operators take one or more values (Operands/Variables) and yields another value. After making, we can call that an expression.

### Example of Operator and Operands
“`php

“`

In the above example –
1. 10 = Operand
2. 20 = Operand
3. `+` = Operator

Or, this could be also done with Variable –
“`php
<?php
$number1 = 10;
$n
