The below code will display the sum of two numbers:
<?php $a=5; $b=6; $c=$a+$b; echo "Sum is: $c"; ?>
OUTPUT:
Sum is: 11
Explanation: There are two variables $a and $b. What we did is just took another variable $c and assigned its value with the summation of $a and $b.
Then just simply echo out this Sum is: $c
As $c is now assigned with $a+$b so it will display 11.

Add two numbers in PHP using HTML form
Here we gonna create a PHP file where the user can input the value of two numbers in an HTML form. When the user will press the submit button or hit enter the PHP script will process the request and echo out the summation of the two numbers. Below is the code to do that
Please Note That:
<form action="index.php" method="post">
I have used index.php in form action field as The PHP file is named as index.php. You have to use your file name whatever you have given to create your PHP file.
And one more thing is that you can use GET method if you want.
<!DOCTYPE html>
<html>
<head>
<title>Summation Of two numbers using PHP</title>
</head>
<body>
<form action="index.php" method="post">
<input type="numbers" name="num1">
<input type="numbers" name="num2">
<input type="submit" name="submit">
</form>
</body>
</html>
<?php
if (isset($_POST['num1']) && isset($_POST['num2'])) {
$result=$_POST['num1'] + $_POST['num2'];
echo $result;
}
?>If you run this PHP file on your server you will get two text boxes. Enter two numbers and click on submit. The result will be displayed.
