MYSQL查询错误(结果数组)

[英]MYSQL Query Error (Result Array)

I have this result 我有这个结果

Furni Count: Array

My code is 我的代码是

$query2 = mysql_query(
                "SELECT COUNT(DISTINCT id) FROM items
                 WHERE base_item='" . $weekly2['furniture_id'] . "'"
           );

$OwnerCount = mysql_fetch_array($query2);
echo "<tr><td width=\"92%\" >Owner Count: $OwnerCount<form><input type=\"submit\" value=\"Owner Last Online\"></form></td></tr>";

It's because your echo ing an array, try print_r($Ownercount); 这是因为您echo了一个数组,所以请尝试print_r($Ownercount); and you should see the array (and the keys). 并且您应该看到数组(和键)。

Example: 例:

echo $Ownercount[0];

Should return the first key in the array (which is probably what you want). 应该返回数组中的第一个键(可能是您想要的)。

you can put an alias on the query, like this : 您可以在查询上放置一个别名,如下所示:

COUNT(DISTINCT id) as total

and then call 然后打电话

$Ownercount["total"];
