如何在函数中获得用户好听的名字？目前我用头像获得了它，但不知道如何获得用户好听的名字：

$table = $wpdb->prefix . "thumbsup_info";
    $result = $wpdb->get_results("SELECT userid FROM $table WHERE postid = '$postid' LIMIT 10", ARRAY_A);
    $total_user = $wpdb->num_rows;
    for($i=0; $i <$total_user ; $i++)
        {   
            $userid.= get_avatar($result[$i]['userid'],100);


        }
    return $userid;

我有一个数组$ captions我想检查内部是否至少有一个值.数组看起来像这样:

Array
(
    [0] => 84
    [1] => 
    [2] => 82
    [3] => 
    [4] => 
    [5] => 
    [6] => 
    [7] => 
    [8] => 
    [9] => 
)

我的方式检查是否有"超过0","超过1"......

if (count($captions) > 0)   { echo '<br>bigger than 0';}
if (count($captions) === 1) {echo '<br>is 1';};
if (count($captions) > 1)   {echo '<br>gbigger than 1';};
if (count($captions) > 2)   {echo '<br>bigger than 2';}

但是:它给了我这个数组以上结果:

bigger than 0
bigger than 1
bigger than 2

"大于2"不应该,因为数组只包含两个值？我错了什么？
