我正在尝试使用删除和编辑用户的最终选项来查看当前用户。$dbc 在我的 header.html 文件中的另一个文件中。我收到的唯一不包括页眉/页脚的输出是：警告：mysqli_fetch_array() 期望参数 1 是 mysqli_result，在 C:\xampp\htdocs\Kyle_Site\Programming Rite\controle\view_users.php 中给出的布尔值在线76 编辑 删除 姓 名 注册日期

这是我的 header.html 的顶部：

<?php
require 'connect.inc.php';
require 'core.inc.php';
if (!loggedin()) 
    {
        header("Location: index2.php");
        exit;
    }
?>

这是我的 connect.inc.php：

<?php
$mysql_host='209.129.8.3';
$mysql_user='47278';

$conn_error='Could not connect';
$mysql_db='47278';

$dbc = @mysqli_connect ($mysql_host, $mysql_user, $mysql_pass);
if(!@mysql_connect($mysql_host, $mysql_user, $mysql_pass) || !@mysql_select_db($mysql_db)){
die($conn_error);
}

?>

我进行了更改并删除了 3 个@，现在我有一个新错误以及两个旧的警告：mysqli_fetch_array() 期望参数 1 是 mysqli_result，在 C:\xampp\htdocs\Kyle_Site\Programming Rite 中给出的布尔值\controle\view_users.php 第 21 行

the problem is here:

$r = @mysqli_query ($dbc, $q);

remve the @ infront of it and you will see the mySQL error that gives you. This way you suppressed the error and it results as FALSE, which is why the next lines fails after.
