由于某种原因,项目"description"返回NULL以下代码:

<?php
include('db.php');

$result = mysql_query('SELECT * FROM `staff` ORDER BY `id` DESC LIMIT 2') or die(mysql_error());
$rows = array();
while($row = mysql_fetch_assoc($result)){
    $rows[] = $row;
}

echo json_encode($rows);
?>

这是我的数据库的架构:

CREATE TABLE `staff` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `name` longtext COLLATE utf8_unicode_ci,
  `description` longtext COLLATE utf8_unicode_ci,
  `icon` longtext COLLATE utf8_unicode_ci,
  `date` longtext COLLATE utf8_unicode_ci,
  `company` longtext COLLATE utf8_unicode_ci,
  `companyurl` longtext COLLATE utf8_unicode_ci,
  `appurl` longtext COLLATE utf8_unicode_ci,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM AUTO_INCREMENT=5 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci
