PHP/ARRAY/HTML TABLE -- How come this repeats the same thing across the whole <td>? - html

Question

Im trying to turn an array of friends names: $friends['name'] from the Facebook Graph API into a table with 4 columns across with one persons name in each box.
The problem:
I have it making a table and putting peoples names in the cells of the table, however, it repeats each persons name across all 4 in a row instead of putting a unique name in each box. However the next row starts with a new name.
I would greatly appreaciate anybody who can help point out where Ive gone wrong and help me correct it:
<?
$friends_url = "https://graph.facebook.com/".$user_id."/friends?access_token=".$access_token;
$friends_json = file_get_contents($friends_url);
$friends_data = json_decode($friends_json, true);
$friends_total = count($friends_data['data']);
$cols = 4;
for ($i = 0; $i < $friends_total; $i++)
{
$friends = $friends_data['data'][$i];
echo "<tr>";
for ($c=0; $c<$cols; $c++)
{
$n = $i+$c;
if ( $n < $friends_total)
{
echo "<td>".$friends['name']."</td>";
}
else
{
echo "<td></td>";
}
}
echo "</tr>";
$i += ($c-1);
}
?>

Because you're looping 4 times for each friend and your loop counter for 'columns' is inside that loop, try something more like this:
$cols = 4;
$current_col = 0;
echo "<tr>";
foreach ($friends_data['data'] as $friend)
{
echo "<td>".$friend['name']."</td>";
if (($current_col++)%$cols == 0){
echo "</tr><tr>";
}
}
while (($current_col++)%$col !=0){
echo "<td> </td>";
}
echo "</tr>";
This loops through all the friends, keeping a counter of how many have been printed. After 4 (/or whatever $cols is set to) it spits out a new row
When the friends are all printed out, it starts a new loop to fill in the end of the last row with empty cells, then ends the row
