发布时间：2022-04-30 发布网站：脚本宝典

脚本宝典收集整理的这篇文章主要介绍了php – 致命错误：不支持的操作数类型，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

我继续收到以下错误,我想知道如何解决它.

Fatal error: Unsupported operand tyPEs on line 97

它围绕下面列出的代码区域.如果需要,我可以列出完整的代码.

PHP 代码

$total_rating_points = MysqLi_fetch_array($result);
if (!empty($total_rating_points) && !empty($total_ratings)){
    $avg = (round($total_rating_points / $total_ratings,1));
    $Votes = $total_ratings;
    echo $avg . "/10  (" . $Votes . " Votes cast)";
} else {
    echo '(no Votes cast)';
}

这是第97行

$avg = (round($total_rating_points / $total_ratings,1));

这是完整的代码.

function getratingText(){
    $dbc = MysqLi_connect ("localhost","root","","sITename");

    $page = '3';

    $sql1 = "SELECT COUNT(*) 
             From articles_grades 
             WHERE users_articles_id = '$page'";

    $result = MysqLi_query($dbc,$sql1);

    if (!MysqLi_query($dbc,$sql1)) {
            PRint MysqLi_error($dbc);
            return;
    }

    $total_ratings = MysqLi_fetch_array($result);

    $sql2 = "SELECT COUNT(*) 
             From grades 
             JOIN articles_grades ON grades.id = articles_grades.grade_id
             WHERE articles_grades.users_articles_id = '$page'";

    $result = MysqLi_query($dbc,$sql2);

    if (!MysqLi_query($dbc,$sql2)) {
            print MysqLi_error($dbc);
            return;
    }

    $total_rating_points = MysqLi_fetch_array($result);
    if (!empty($total_rating_points) &amp;& !empty($total_ratings)){
        $avg = (round($total_rating_points / $total_ratings,1));
        $Votes = $total_ratings;
        echo $avg . "/10  (" . $Votes . " Votes cast)";
    } else {
        echo '(no Votes cast)';
    }
}
