Question

I have the following PHP array structure:

$set = array();
$set[] = array('firstname'=>'firstname 1',
           'lastname'=>'lastname 1',
            "bio"=>array('paragraph 1 of the bio, 'paragraph 2 of the bio','paragraph 3 of the bio'),
           );

I then access the array with the following:

  <?php $counter = 0;
  while ($counter < 1) :  //1 for now
  $item = $set[$counter]?>  

    <h1><?php echo $item['firstname'] ?></h1>
    <h1><?php echo $item['lastname'] ?></h1>

  <?php endwhile; ?>

I’m uncertain how I can loop through the “bio” part of the array and echo each paragraph.

So as a final output, I should have two h1s (first and last name) and three paragraphs (the bio).

How can I go about doing this?

You don’t need to use a manual counter, you can use foreach. It’s generally the easiest way and prevents off-by-one errors.

Then you need a second inner loop to loop through the bio.

<?php foreach ($set as $item): ?>  
    <h1><?php echo $item['firstname'] ?></h1>
    <h1><?php echo $item['lastname'] ?></h1>
    <?php foreach ($item['bio'] as $bio): ?>
        <p><?php echo $bio; ?></p>
    <?php endforeach; ?>
<?php endforeach; ?>

On a related note; you probably want to look into escaping your output.
