Courses Plus Student 2,526 PointsNeed help outputting values from an multidimensional array.
I am trying to get through the code test after PHP Arrays and Control Structures. I believe my code is working code but I keep getting a "Try Again" message. I am not sure what I am missing.
<?php
//edit this array
$contacts[] = array(
'name' =>'Alena Holligan',
'email' => 'alena.holligan@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Dave McFarland',
'email' => 'dave.mcfarland@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Treasure Porth',
'email' => 'treasure.porth@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Andrew Chalkley',
'email' => 'andrew.chalkley@teamtreehouse.com'
);
echo '<ul>/n';
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo '<li>'.$contacts[0]['name']. ' : ' . $contacts[0]['email']. '</li>';
echo '<li>'.$contacts[1]['name']. ' : ' . $contacts[1]['email']. '</li>';
echo '<li>'.$contacts[2]['name']. ' : ' . $contacts[2]['email']. '</li>';
echo '<li>'.$contacts[3]['name']. ' : ' . $contacts[3]['email']. '</li>';
echo '</ul>';
?>

tags had a new line character "\n" after them, which is either lacking or incorrect in your code.
It's also worth noting that PHP only processes escape characters when you use double quotes for strings, not single quotes. So in addition to adding the new line escape character you need to change the single quotes to double quotes.
Like this:
<?php
//edit this array
$contacts[] = array(
'name' =>'Alena Holligan',
'email' => 'alena.holligan@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Dave McFarland',
'email' => 'dave.mcfarland@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Treasure Porth',
'email' => 'treasure.porth@teamtreehouse.com'
);
$contacts[] = array(
'name' =>'Andrew Chalkley',
'email' => 'andrew.chalkley@teamtreehouse.com'
);
echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
echo '<li>' . $contacts[0]['name'] . ' : ' . $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";
?>
