PHP Basic Math Functions



Basic Math Functions

PHP is pretty much like a big calculator.
You can do basic math functions right in your variable. A variable equal to whatever equations you have and then displays the output on the screen. Bunch of stuff you can do, like addition, subtraction, multiply, division, remainder, etc.

Example: 1

        <?php
        $anything = 10;
        echo $anything;
        ?>

Output

10

Addition

Example: 2

        <?php
       $anything = 10+500;
       echo $anything;
        ?>

Output

510

Subtraction

Example: 3

        <?php
       $anything = 10-500;
       echo $anything;
        ?>

Output

-490

Adding two variables

Example: 3

        <?php
       $anything = 55;
       $something = 45;
       echo $anything + $something;
        ?>

Output

100
