php数字

Question

这里有一些数字,从1到50,如何输出数字5,15,25,35,45？

我使用这样的代码,但也会输出10,20,30,40,50.谢谢.

<?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;
}

要么

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

要么

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

或其任何其他组合.
