PHP Index

In order to become familiar with PHP programming structures and commands, we will build various PHP pages. Sections of this page will explain each PHP command, provide a link to a working sample, and detail the working sample's PHP code. Let's get started:

Math

Math is fairly easy with PHP. You are already familiar with the most common math operators:

+ Addition

- Subtraction

* Multiplication

/ Division

% Modulus (returns the remainder between two numbers)

For example: math.php

 <html>

  <head>

  <title>math.php</title>

  </head>

  <body>

            <?php

            

            $additionanswer = 100+10;

            //Online Calculator

            

            Print("<h1> Online Calculator </h1>");

            

            //Display math output

            print ("100 + 10 = " . (100 + 10). " Addition <br>");

            print ("100 - 10 = ". (100-10) ." Subtraction <br>");

            print("100 * 10 = ". (100*10) ." Multiplication <br>");

            print("100 / 10 = ". (100/10) ." Division <br>");

            print("99 % 10 = ". (99%10) ." Modulus (the remainder!) <br>");

            

            ?>

            

  </body>

  </html>

In addition to the main math operators, there are also many math functions to use, including abs (absolute value), is_nan (is not a number), max (maximum), and min (minimum).
