从函数中获取最后数据

Question

我有这个代码，得到我在facebook上的最后状态:-

<?php 
/*---------------------------------------------------------------------------------*/
# Gets the data from a URL
/*---------------------------------------------------------------------------------*/
function get_data($url) {
    $ch = curl_init();
    $timeout = 5;
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $data = curl_exec($ch);
    curl_close($ch);
    return $data;
}
  $data = get_data("[url]");
  $result = json_decode($data);
  $latest_post =  $result->data[0];
  $latest_post_text = $latest_post->message;
  $latest_post_link = $latest_post->actions[0]->link;
?>

当我像这样打印时:-

<a href="<?php echo $latest_post_link ?>"><?php echo $latest_post_text ?></a>

它只显示我最后的状态。我需要得到最后3个状态。我怎么能做到呢?

你需要循环显示数据

<?php 
  $counter = 0; // Add a counter to your code
  foreach ($result->data as $latest):
  $counter++; //Icrement your counter
  if ($counter > 3) { break; } // Stop foreach after 3 loops
?> 
<a href="<?php echo $latest->actions[0]->link; ?>"><?php echo $latest->message; ?></a>
<?php endforeach; ?>
