添加此内容并查看它回显的内容
function show_post($user_id)
{
global $database;
$post = array();
$sql = sprintf("SELECT body,stamp FROM post WHERE user_id = '%s' ORDER BY stamp DESC ",$user_id);
$result = $database->query($sql);
while( $data = $database -> fetch_array($result))
{
echo '<pre>'; print_r($data); echo '</pre><br />';
$post[] = array(
'user_id' => $user_id,
'body' => $data->'body',
'stamp' => $data->'stamp'
);
}
return $post;
}
除非print_r($ data)打印出奇怪的东西,否则我看不出那段代码有什么问题。可能与您正在使用的数据库类有关。
