php - 如何在 PDO 中打印 while() 循环

Question

我有一个包含 4 列的数据库表:Name , Comment , Star , Status .

我想在一个页面上显示表的所有记录。这是我的查询:

$sth = $this->db->prepare("SELECT * FROM comment WHERE status = 1");
$sth->setFetchMode(PDO::FETCH_ASSOC);
$sth->execute();

$reviews = array();

while($row = $sth->fetch()){    
    $reviews->name = $row['name'];
    $reviews->comment = $row['comment'];
    $reviews->star = $row['star'];
}

return $reviews;

但是，var_dump($reviews)显示array(0) { } 。我哪里出错了？

Answer 1

您要使用 -> 运算符将数组作为对象访问，请改用 []。

$reviews = array();

while($row = $sth->fetch()){    
    $reviews[]['name'] = $row['name'];            # <---- Change them like this.
    $reviews[]['comment'] = $row['comment'];
    $reviews[]['star'] = $row['star'];
}
