Question

尝试获取表格中的最后一行，但抛出错误......

  

'警告：mysqli_fetch_assoc（）期望参数1为   mysqli_result，'

中给出的字符串

$recents = "SELECT * FROM list ORDER BY id DESC LIMIT 1";
 Ah yes, forgot to execute query here
if ($result = mysqli_fetch_assoc($recents)) {
    $mName = $result['name'];
    $mDesc = $result['description'];
    $mCost = $result['cost'];
}

Answer 1

您需要传递查询结果，而不是查询字符串。

$sql = "SELECT * FROM list ORDER BY id DESC LIMIT 1";
$recent = mysqli_query($connetion, $sql);

Answer 2

您忘记使用该语句来运行查询

$results=mysqli_query($conn,$recents)
