“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
