试图计算投票表中的所有投票，但我在第153行收到错误

Question

致命错误：不能在第153行的/home/students/gar0349/public_html/project2voting.php中使用stdClass类型的对象作为数组

<?php
$totalvotes = ("SELECT COUNT(*) AS total FROM voting WHERE votes >= 0 ");
    $totalvotesresults = mysql_query( $totalvotes )
or die( "Could not get total votes " .mysql_error() );
$data = mysql_fetch_object( $totalvotesresults );
echo "<div>Total number of votes is ". $data['total'] ."</div>\n";;
?>

Answer 1

$data = mysql_fetch_object( $totalvotesresults );

您正在获取对象，因此您需要使用

$data->total;


echo "<div>Total number of votes is ". $data->total ."</div>\n";;

Answer 2

$data是一个对象，而不是一个数组 尝试：

echo "<div>Total number of votes is ". $data->total ."</div>\n";

Answer 3

    <?php
$totalvotes = "SELECT COUNT(*) AS total FROM voting WHERE votes >= 0 ";
    $totalvotesresults = mysql_query( $totalvotes )
or die( "Could not get total votes " .mysql_error() );
$data = mysql_fetch_object( $totalvotesresults );
echo "<div>Total number of votes is ". $data->total ."</div>\n";
?>

从第一行删除第一个支架QUery ..并且aslo

    echo "<div>Total number of votes is ". $data->total ."</div>\n";
