首先需要ul有1 li，每个ul有5 li

Question

I need this type of structure in PHP foreach loop. and i tried this code :

<ul>
    <li>1</li>
</ul>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
</ul>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
</ul>
<ul>
    <li>1</li>
    <li>2</li>
    <li>3</li>
    <li>4</li>
    <li>5</li>
</ul>

i tried this condition inside loop and working fine but i need 1 li on first ul.

<?php
$counter = 1;
foreach( $myposts as $post ) :

  setup_postdata($post); 

  if ($counter % 5 == 1) {
    echo '<ul>';
  }
  echo '<li>testing ...</li>'

  if($counter % 5 == 0) {
    echo '</ul>';
  }
  $counter++;
endforeach;
?>

any one extend my logic ??

Answer 1

This is what I came up with:

$myposts = array(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16);

$counter = 0;
echo '<ul>';
foreach( $myposts as $k=>$post ) :
    //setup_postdata($post); 
    echo '<li>'.$post.'</li>';
    if($counter==0 || $counter==5){
        echo "</ul>".($k!=count($myposts)-1 ? "<ul>" : "");
        $counter = 0;
    }
    $counter++;
endforeach;
if($counter==5){
    echo '</ul>';
}

This largest misconception most people don't bother to close that last tag (in your case ul), or they open a new tag (in your case ul) when they shouldn't.

P.s. I had to comment setup_postdata for this to work.

Note: Adding or removing elements from the array will not effect the structure of 1,5,5,...,(then remainder depending on what is left)
