How do I add a name and an email to the page from the Multi-dimensional array key-value pairs?

<?php
//edit this array
$contacts = array(
  array('name'=>'Alena Holligan',
        'email'=>'alena.holligan@teamtreehouse.com'
       ), 
  array('name'=>'Dave McFarland',
        'email'=>'dave.mcfarland@teamtreehouse.com'
       ),
  array('name'=>'Treasure Porth',
        'email'=>'treasure.porth@teamtreehouse.com'
       ),
  array('name'=>'Andrew Chalkley',
        'email'=>'andrew.chalkley@teamtreehouse.com'
       )
);

echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li> var_dump($contacts[0]['name']);var_dump($contacts[0]['email']);</li>\n";
echo "<li> var_dump($contacts[1]['name']);var_dump($contacts[1]['email']);</li>\n";
echo "<li> var_dump($contacts[2]['name']);var_dump($contacts[2]['email']);</li>\n";
echo "<li> var_dump($contacts[3]['name']);var_dump($contacts[3]['email']);</li>\n";
echo "</ul>\n";
