在PHP中为数组中的图像提供链接

I have a trouble giving link to the image in a array.

$sponsors = array(

array('id-1','tier1','app','http://www.google.com/'),

Here is the loop across the array, where

<?php
  foreach($sponsors as $company)
  {
    echo'
    <li data-id="'.$company[0].'" data-type="'.$company[1].'" style="">
        <img src="/wp-content/themes/sustainability/assets/images/members/'.
          $company[1].'-'.$company[2].
          '.jpg" alt="More about '.$company[2].'" />
        <a href="#"></a>  
    </li>';
  }

    ?>

Would it not be easier to build an associative array?

array('id' => 'id-1','data-type' => 'tier1', 'key' => 'app', 'link' => 'http://www.google.com/'),
//......etc etc

Allowing you to loop through it and print it out as you'd like?

<?php
  foreach($sponsors as $company)
  {
    echo'
    <li data-id="'.$company['id'].'" data-type="'.$company['data-type'].'" style="">
        <img src="/wp-content/themes/sustainability/assets/images/members/'.
          $company['data-type'].'-'.$company['key'].
          '.jpg" alt="More about '.$company['key'].'" />
        <a href="#"></a>  
    </li>';
  }

?>

^{Note: I don't know what your key is called? So you'll want to change that to whatever it is? probably product right?}
