Question

我正在尝试使用两个GET请求遍历MYSQL数据库。但它似乎没有用？这是我回来的信息：

Warning: mysqli_stmt::bind_result(): Number of bind variables doesn't match number of fields in prepared statement in /path on line 13
[]

这是我的代码：

$con = mysqli_connect('localhost','user','pass','db');

$limit = $_GET['limit'];
$lastid = $_GET['lastid'];



$all_news = $con->prepare("SELECT * FROM news ORDER BY news.date DESC LIMIT ?, ?"); 
$all_news->bind_param("ii", $lastid, $limit);
$all_news->execute();
$all_news->bind_result($id, $url, $image_url, $date, $news_text, $referer_img);

$rows = array();
while($all_news->fetch()) {
    $rows[] = array($id, $url, $image_url, $date, $news_text, $referer_img);
}
print json_encode($rows);

Answer 1

您有select *，但只将一个变量绑定到结果列。如果您只想要一列，则只显式选择一列：

SELECT field_you_want FROM news ...

Answer 2

该错误是因为您只绑定了一个参数，并且您的语句包含两个变量。

循环遍历mySQL并打印为json
