如何在一行中運行兩個更新查詢？

Answer 1

使用您可以實現的 mysqli 擴展，您可以使用 mysqli_multi_query 運行多個查詢：

$sql = "UPDATE user SET password = '$new_password' WHERE temp_url = '$temp_code';";
$sql .= "UPDATE user SET temp_url = '' WHERE user_name = '$user_name_frmdb';";

// Execute multi query
if (mysqli_multi_query($con, $sql)) {
    // Query successful
}
