Integer type and behavior

📖 Scenario: You are working on a simple PHP script that deals with whole numbers. Understanding how integers work in PHP will help you manage numbers correctly in your programs.

🎯 Goal: Learn how to create integer variables, use integer operations, and display integer values in PHP.

📋 What You'll Learn

Create integer variables with exact values

Use a helper variable to store a number

Perform an integer addition operation

Print the final integer result

💡 Why This Matters

🌍 Real World

Integers are used in many real-world applications like counting items, calculating totals, or managing scores.

💼 Career

Understanding integer behavior is essential for backend development, data processing, and any programming job involving numbers.

1

Create integer variables

Create two integer variables called num1 and num2 with values 10 and 20 respectively.

PHP

<?php

// Create integer variables num1 and num2 with values 10 and 20
// Your code here

Need a hint?

Use the = sign to assign values to variables.

2

Add a helper variable

Create an integer variable called increment and set it to 5.

PHP

<?php

$num1 = 10;
$num2 = 20;

// Create an integer variable increment with value 5
// Your code here

Need a hint?

Remember to end each statement with a semicolon.

3

Calculate the sum

Create an integer variable called total that adds num1, num2, and increment together.

PHP

<?php

$num1 = 10;
$num2 = 20;
$increment = 5;

// Add num1, num2, and increment and store in total
// Your code here

Need a hint?

Use the + operator to add numbers.

4

Display the result

Use echo to print the value of total.

PHP

<?php

$num1 = 10;
$num2 = 20;
$increment = 5;
$total = $num1 + $num2 + $increment;

// Print the total
// Your code here

Need a hint?

Use echo $total; to display the number.
