I'm getting a check for spacing error, but I'm not sure what what its trying to tell me.

Im creating multi-dimensional arrays but i keep getting the error 'check for spacing'. What does it mean? What is it trying to tell me?

index.php 
<?php
//edit this array
$contacts = array(['name' => 'Alena Holligan', 'email' => 'alena.holligan@teamtreehouse.com',],
                  ['name' =>'Dave McFarland', 'email' => 'dave.mcfarland@teamtreehouse.com'],
                  ['name' => 'Treasure Porth', 'email' => 'treasure.porth@teamtreehouse.com'],
                  ['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";

Hi Michael,

I believe your error is where you are trying to do a concatenation with the colon :

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";

Thank you for replying, but that I don't think that is the issue. I'm concatenating with periods and the colon is inside a string as output html.

The answer was that I declared the arrays wrong. $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'];

I'm not sure why I was allowed to move forward from step two, but the code above was how I fixed it.
