问题描述
我有这个功能:
function get_following($user_id) {
global $conn;
$stmt = $conn->prepare("SELECT * FROM following WHERE `follower_id`=:user");
$stmt->bindParam(':user', $user_id, PDO::PARAM_INT);
$stmt->execute();
$following =$stmt->fetch(PDO::FETCH_ASSOC);
return $following;
}
以下
表格如下所示:
|user_id|follower_id|
| 2 | 5 |
| 3 | 5 |
| 4 | 5 |
现在的问题是,当我实际调用该函数时,它只从表中选择一行,其中我的 follower_id = 5.
Now the problem is when I actually call the function it only selects one of the rows from the table, where my follower_id = 5.
推荐答案
$following 必须是一个行数组.您实际上只是在获取第一行.使用 PDOStatement::fetchAll()
获取它,如下所示:
$following will have to be an array of rows. You are actually only fetching the first row. Fetch it using PDOStatement::fetchAll()
, like this:
$following = $stmt->fetchAll(PDO::FETCH_ASSOC);
