Question

Here are some numbers, from 1 – 50, how to output the number 5,15,25,35,45 ?

I use some code like this, but is also will output 10,20,30,40,50. Thanks.

<?php
  for ($n = 1; $n <= 50; $n++) {
    if ($n%5 == 0 ){
      echo "<p>".$n."<p><br />"; // do stuff
    }   
  }
?>

Answer 1

for ($n = 5; $n <= 45; $n += 10) {
    echo $n;
}

or

echo join(', ', range(5, 45, 10));

or

foreach (range(5, 45, 10) as $n) {
    echo $n;
}

or any other combination thereof.
