  1. Dear developers, I was solving problems to improve my algorithmic abilities. So, here is one of them: I need to "echo" all the prime numbers to the browser up to certain number. So, if the number is 8, for example, I need to echo 2,3,5 and 7. here is my code: $a = 100; for($i = 2; $i<=$a; $i++) { if($i == 2) { echo "2</br>"; } for($j =3; $j <= ceil($i/2); $j = $j + 2) { if($i % 2 == 0) { break; } if ($i % $j == 0) { break; } else { continue; } } } not working properly! Please Help !!!
