If-else execution flow in PHP - Mini Project: Build & Apply

If-else execution flow

📖 Scenario: You are creating a simple program to check if a person is old enough to vote. Voting age is 18 years or older.

🎯 Goal: Build a PHP program that uses if-else statements to decide if a person can vote based on their age.

📋 What You'll Learn

Create a variable called age with a specific value.

Create a variable called voting_age set to 18.

Use an if-else statement to check if age is greater than or equal to voting_age.

Print "You can vote." if the person is old enough.

Print "You cannot vote yet." if the person is too young.

💡 Why This Matters

🌍 Real World

Checking age eligibility is common in websites for voting, driving licenses, or age-restricted content.

💼 Career

Understanding if-else logic is fundamental for programming jobs that require decision making and flow control.

1

Create the age variable

Create a variable called age and set it to 20.

PHP

<?php

// Create a variable called age and set it to 20

Need a hint?

Use $age = 20; to create the variable.

2

Set the voting age

Create a variable called voting_age and set it to 18.

PHP

<?php

$age = 20;

// Create a variable called voting_age and set it to 18

Need a hint?

Use $voting_age = 18; to create the variable.

3

Write the if-else statement

Write an if statement that checks if $age is greater than or equal to $voting_age. If true, print "You can vote.". Otherwise, print "You cannot vote yet.".

PHP

<?php

$age = 20;
$voting_age = 18;

// Write an if-else statement to check voting eligibility

Need a hint?

Use if ($age >= $voting_age) { ... } else { ... } and print() inside.

4

Display the result

Run the program and print the output to show if the person can vote or not.

PHP

= $voting_age) {
    print("You can vote.");
} else {
    print("You cannot vote yet.");
}

// Output is already printed by print statements

Need a hint?

The program already prints the result. Just run it to see the output.
