SUM计数的输出结果

Question

我对我的数据库有此查询，它工作正常，我在PHPMyAdmin中对其进行了测试。 我的问题是我试图在页面上显示结果，但是我得到的是空白输出而没有错误

我在做什么错了？

$count_fields = "SELECT SUM(agent_status = '1' ) AS 'agent'
    ,  SUM(agent_status = '0' ) AS 'agentoff'
     ,  SUM(admin_status = '0' ) AS 'admin'
      ,  SUM(user_id = '$id' ) AS 'user'
FROM property WHERE user_id = '$id'";
$count_res = $conn->prepare($count_fields);
$count_res->execute();
$count = $count_res->fetchAll();

我创建了一个

之类的foreach循环

    foreach ($count as $cnt){
echo $cnt['agent']
}

但结果为空白...

foreach ($count as $cnt){
    echo $cnt['agent'] ;// please add ; 
}
