PHP:警告:sort()期望参数1是数组,给定资源

我是PHP和MySQL的新手,我只是想不出这个.我在论坛周围搜索过但没有找到我能理解的答案.我最初使用的是mysql_fetch_assoc(),但我只能搜索数字,并且在搜索字母时也收到了错误.我希望我在这里走在正确的轨道上.提前感谢您的帮助!

$con = mysqli_connect($hostname,$username,$password) or die ("<script language='javascript'>alert('Unable to connect to database')</script>");
mysqli_select_db($con, $dbname);

if (isset($_GET['part'])){
    $partid = $_GET['part'];
    $sql = 'SELECT * 
        FROM $usertable 
        WHERE PartNumber = $partid';

    $result = mysqli_query($con, $sql);
    $row = mysqli_fetch_assoc($result);

    $partnumber = $partid;
    $nsn = $row["NSN"];
    $description = $row["Description"];
    $quantity = $row["Quantity"];
    $condition = $row["Conditio"];
}
