Write a PHP script to displays numbers between 100 and 150 divisible by 4

Description: Write a PHP script to display the numbers between 100 and 150 that are divisible by 4.

Rules and hints:

• Use a loop and an if condition.
• Use the modulus operator (%). A number is divisible by 4 when $i % 4 is 0.

PHP program for numbers divisible by 4

<?php
for ($i = 100; $i <= 150; $i++) {
    if ($i % 4 == 0) {
        echo $i . " ";
    }
}
?>

Output:

How it works

• The loop checks every number from 100 to 150.
• % gives the remainder of the division. If the remainder is 0, the number is divisible by 4, and it is printed.

A shorter way

Since 100 is divisible by 4, you can start from 100 and add 4 in every round. You do not need the if condition.

<?php
for ($i = 100; $i <= 150; $i += 4) {
    echo $i . " ";
}
?>
