从SQL查询创建数组

Question

我使用以下代码将数据从WordPress SQL数据库提取到数组......

global $wpdb;
$blogusers = get_users('blog_id=1&orderby=nicename&role=seller');

foreach ($blogusers as $user) {
    $count = $wpdb->get_results("SELECT COUNT(*) as count FROM wp_mymeta1 WHERE value='$user->user_login'");
    $total = $count[0]->count;

    $arrData=array("Seller"=>"$user->user_login","Total"=>"$total");
    $arrRtn=array();
    array_push($arrRtn, $arrData);

    print_r($arrRtn);
}

它返回以下数组....

Array ( [0] => Array ( [Seller] => 76 [Total] => 989 ) )
Array ( [0] => Array ( [Seller] => 33 [Total] => 765 ) )
Array ( [0] => Array ( [Seller] => 93 [Total] => 743 ) )

但我试图将数据放在一个看起来像这样的数组中......

var $example_data = array(
        array(
            'Seller'    => '76',
            'Total'     => '989'
        ),
        array(
            'Seller'    => '33',
            'Total'     => '765'
        ),
        array(
            'Seller'    => '93',
            'Total'     => '743'
        ),
    );

我哪里错了？
