試圖計算投票表中的所有選票，但在第153行出現錯誤

Question

致命錯誤：無法在第153行的/home/students/gar0349/public_html/project2voting.php中將stdClass類型的對象用作數組

<?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 );

您正在獲取作為對象，因此您需要使用as

$data->total;


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

Answer 2

$data是一個對象，而不是數組。
嘗試：

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";
?>

從第一行查詢中刪除第一個托架..和aslo

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