如何在三个帖子后显示横幅？

Question

Below is the code to display the post. That loads every 10 posts. And I want to display banner after 3 post. Can someone tell me, code to display banner after 3 post? By completing the code below. Thank you so much for your help.

<?php
        $stories = Wo_GetPosts(array('limit' => 10));
        if (count($stories) <= 0) {
          echo Wo_LoadPage('story/no-stories');
        } else {
          foreach ($stories as $wo['story']) {
            echo Wo_LoadPage('story/content');
          }
        }
        ?>

You are trying to use count() in a way that this function is not intended. Per the PHP documentation:

Counts all elements in an array, or something in an object. http://php.net/manual/en/function.count.php

What you need to do is create a counter variable that increments within your foreach loop, and when it hits 3 outputs the banner. Your code might look something like this:

<?php

  $stories = Wo_GetPosts(array('limit' => 10));

  // No stories; output error
  if (count($stories) <= 0) 
    echo Wo_LoadPage('story/no-stories');

  // Stories exist; show them!
  } else {

    $count = 0;

    // Loop through $stories
    foreach ($stories as $wo['story']) {
      // Increment the value of $count by +1
      $count++; 

      if ($count == 3) {
        // Output my Banner here
      }

      echo Wo_LoadPage('story/content');
    }
  } 

?>

One thing I would note is that the above code only outputs a banner one time; when the value of $count is 3. You could adjust this to run ever 3rd story by changing the match from if ($count ==3) to if ($count % 3 == 0) which essentially reads as If the value of $count is divisible by 3.
