"Basic Operators

"The standard arithmetic operators are available in PHP and
these are the same as in any other language:

+ Addition of numbers (20+10)

- Subtraction of numbers (20-10)

* Multiplication of numbers (20*10)

/ Division of numbers (20/10)

"When setting up or assigning variables, you can set the initial
value to the result of a mathematical equation, as in the following
example:

$result = 2+2; // $result will be equal to 4

For subtraction and addition there's also a very handy shortcut
or two which are great for loop handling, these shortcuts are used
by appending either a double + or a double - after the variable
name:

$a = 1; // $a equals to 1

$a++; // $a equals 2

$a--; // $a once again equals 1
