Adding Two Numbers in PHP

Syntax

In PHP, you can add two numbers using the + operator.

$sum = $num1 + $num2;

Example

Below is an example of a PHP script that adds two numbers together:

$num1 = 5;
$num2 = 3;
$sum = $num1 + $num2;
echo "The sum of $num1 and $num2 is $sum.";

Output

When running the above script, you should see the following output:

The sum of 5 and 3 is 8.

Explanation

In the above script, we first define two variables $num1 and $num2 with integer values of 5 and 3. We then add those two variables together using the + operator and store the result in the $sum variable. Finally, we use the echo statement to output the sum of the two numbers in a string.

Use

Adding two numbers together is a basic mathematical operation that is used in a variety of applications, such as calculating totals, averages, and percentages.

Important Points

• In PHP, the + operator is used to add two numbers together.
• Variables must be defined and assigned values before they can be added together.
• The echo statement is used to output the result of the addition as a string.

Summary

Adding two numbers in PHP is a simple process that involves using the + operator and assigning the result to a variable. The resulting value can then be output using the echo statement.
