限制朋友的数量到12个框中显示？

Question

i have a box which displays friends of a user, however, it shows them all and stretched off the canvas of the app. I have them in a table in the box, is there anyway to limit the amount shown to 12 random friends?

this is my code to display friends:

if ($user) {
$user_profile = $facebook->api('/me');
$friends = $facebook->api('/me/friends');

echo '<table>';
foreach ($friends["data"] as $value) {
    echo '<td>';
    echo '<div class="pic">';
    echo '<img src="https://graph.facebook.com/' . $value["id"] . '/picture"/>';
    echo '</div>';
    echo '<font color="white">','<div class="picName">'.$value["name"].'</div>','</font>';
    echo '</td>';
}
echo '</table>';
}
?>

You could, for instance, use the break statement to exit the loop. Use it like this:

if ($user) {
    $user_profile = $facebook->api('/me');
$friends = $facebook->api('/me/friends');

$counter = 1;

echo '<table>';
foreach ($friends["data"] as $value) {
    echo '<td>';
    echo '<div class="pic">';
    echo '<img src="https://graph.facebook.com/' . $value["id"] . '/picture"/>';
    echo '</div>';
    echo '<font color="white">','<div class="picName">'.$value["name"].'</div>','</font>';
    echo '</td>';

    if ($counter >= 12) {
        break;
    }
    $counter = $counter + 1;
}
echo '</table>';
}

A more advanced approach would make use of the array_slice() function, which modifies arrays. To only get at most 12 elements, starting at position 0, of $friends['data'] into the foreach loop, you would write:

// your code...
foreach (array_slice($friends["data"], 0, 12) as $value) {
    // your code...
