Please help, l don't seem to figure this out, l have tried over and over again, but l still can't crack it, help me put it down properly.
<?php
//edit this array
$contacts = array('Alena Holligan', 'Dave McFarland', 'Treasure Porth', 'Andrew Chalkley');
echo "<ul>\n";
//$contacts[0] will return 'Alena Holligan' in our simple array of names.
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";

3,447 PointsIn this case, you access the multidimensional array by first selecting which number item in the array you would like (starting from zero). So:
<?php
$contacts[0]
?>
Would select the array for Alena.
You can then access the properties in the selected array like below:
<?php
$contacts[0]['name']
?>
Therefore, in this task to replace the hard coded values, for each item you would use the code below:
<?php
echo "<li>".$contacts[0]['name']." : ".$contacts[0]['email']."</li>\n";
?>
Then repeat that for the other items, so:
<?php
echo "<li>".$contacts[0]['name']." : ".$contacts[0]['email']."</li>\n";
echo "<li>".$contacts[1]['name']." : ".$contacts[1]['email']."</li>\n";
?>
etc.
Hopefully that helps you.
