Displaying all the numbers between 200 and 600

I have to display all the numbers between 200 and 600 (both numbers inclusive) that are divisible by 8:

for($i=200;$i<=600;$i++)
{
    if($i%8==0)
        echo $i.',';
}

It reaches maximum execution time.

-
Why do you test each number?

Rather than $i++ you can use $i += 8. Then the test becomes redundant.

-
Your output is terminated by ,

...584,592,500,
              ^^^^  Extra trailing comma.

I would do:

printf('%d', 200);
for($i = 208; $i <= 600; $i += 8)
{
    printf(', %d', $i);
}
printf('\n');
