PHP Arrays and Control Structures: Multidimensional Array Coding Challenge

I am struck on Challenge Task 3 of 3 on the Multidimensional Array Coding Challenge of the PHP Arrays and Control Structures course. They are wanting me to replace the names and emails of their original code with my multidimensional array variable. So the original code was

echo "<ul>\n"; echo “<li>Alena Holligan : alena.holligan@teamtreehouse.com</li>\n”; echo "<li>Dave McFarland : dave.mcfarland@teamtreehouse.com</li>\n"; echo "<li>Treasure Porth : treasure.porth@teamtreehouse.com</li>\n"; echo "<li>Andrew Chalkley : andrew.chalkley@teamtreehouse.com</li>\n"; echo "</ul>\n";

And the best I could come up was

echo $contacts[0]['name'] . " : " . $contacts[0]['email'] . "\n"; echo $contacts[1]['name'] . " : " . $contacts[1]['email'] . "\n"; echo $contacts[2]['name'] . " : " . $contacts[2]['email'] . "\n"; echo $contacts[3]['name'] . " : " . $contacts[3]['email'] . "\n"; echo $contacts[4]['name'] . " : " . $contacts[4]['email'] . "\n";

But they won't accept it as correct. Can someone help me?

index.php
<?php
//edit this array
$contacts[] = [
  'name' => "Alena Holligan",
  'email' => "alena.holligan@teamtreehouse.com",
  ];

$contacts[] = [
  'name' => "Dave McFarland",
  'email' => "dave.mcfarland@teamtreehouse.com",
  ];

$contacts[] = [
  'name' => "Treasure Porth",
  'email' => "treasure.porth@teamtreehouse.com",
  ];

$contacts[] = [
  'name' => "Andrew Chalkley",
  'email' => "andrew.chalkley@teamtreehouse.com",

  ];


//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo $contacts[0]['name'] . " : " . $contacts[0]['email'] . "\n";
echo $contacts[1]['name'] . " : " . $contacts[1]['email'] . "\n";
echo $contacts[2]['name'] . " : " . $contacts[2]['email'] . "\n";
echo $contacts[3]['name'] . " : " . $contacts[3]['email'] . "\n";
echo $contacts[4]['name'] . " : " . $contacts[4]['email'] . "\n";

i think the problem must be with the output, the contacts should be in a list .

$contacts = array();

$contacts[] = ['name'=>'Alena Holligan',
                    'email'=>'alena.holligan@teamtreehouse.com'
                   ];

$contacts[] = ['name'=>'Dave McFarland',
                    'email'=>'dave.mcfarland@teamtreehouse.com'
                   ];

$contacts[] = ['name'=>'Treasure Porth',
                    'email'=>'treasure.porth@teamtreehouse.com'
                  ];

$contacts[] = ['name'=>'Andrew Chalkley',
                    'email'=>'andrew.chalkley@teamtreehouse.com'
                   ];

//here i think is where your problem starts 
echo "<ul>\n";

echo "<li>". $contacts[0]['name'] ." : ". $contacts[0]['email'] ."</li>\n";
echo "<li>". $contacts[1]['name'] ." : ". $contacts[1]['email'] ."</li>\n";
echo "<li>". $contacts[2]['name'] ." : ". $contacts[2]['email'] ."</li>\n";
echo "<li>". $contacts[3]['name'] ." : ". $contacts[3]['email'] ."</li>\n";

echo "</ul>\n";

How come the html tags are within double quotes? I thought they are only applied to strings?

Secondly, when echoing the values, why are the values separated rather than putting them together? (i.e. $contacts[0]['name', 'email'])
