PHP PHP Arrays and Control Structures PHP Arrays Multidimensional Arrays

Completed the Multidimensonal array challenge, but still don't think I did it right

The last part of this (echoing in the line items) really gave me trouble. I finally got the correct output, but don't think I did it in the most concise way or as intended.

Was there a better way to do this? I couldn't seem to concatenate both the name and email values on one line.

Here's what I ended up doing:

<?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',
];

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

There is nothing wrong on the way that you resolved this task. In the end it is just what you needed. Another way to complete the challenge I would have used a foreach loop to print the results. As in :

<?php 
echo "<ul><br>";
foreach($contacts as $contact){
  echo "<li>" . $contact['name'] . " : " . $contact['email'] . "</li><br>";
 }
echo "<ul>";
?>

Thanks for the reply! I'm not quite at the foreach stage yet, but nice to have a peek at how that makes it more concise.

After some sleep and looking at your example vs. mine, I realize I was originally making a concatenation error.

I realize now to keep each li echo in one statement I should have done this:

<?php
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";
