<?php

$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";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo "<li> {$contacts[0]['name']}  : {$contact[0]['email']}  </li>\n";
echo "<li> {$contacts[1]['name']}  : {$contact[1]['email']} </li>\n";
echo "<li> {$contacts[2]['name']}  : {$contact[2]['email']} </li>\n";
