How does the for loop increment and the if statement condition work together to output specific numbers in the given PHP code snippet?

The for loop in the given PHP code snippet increments the variable $i by 2 in each iteration. The if statement within the loop checks if $i is divisible by 3 and outputs the number only if it meets this condition. To output specific numbers that are divisible by 3, we can modify the if statement condition to check if $i is divisible by 3 using the modulus operator (%). 

for ($i = 0; $i <= 20; $i += 2) {
    if ($i % 3 == 0) {
        echo $i . "<br>";
    }
}
