这些来自带回附加到它的术语对象数组的单个项目（这就是为什么有些项目有多个条目）。你可以看到，有许多term_id是相同的——我只是在寻找一种方法来使它带回一个唯一的数组（而不是多维的）。我看过这样的文章，但到目前为止还没有这样的运气。有什么建议么？谢谢！

像这样的东西？

$out = array();

foreach($data as $row){
    if(is_array($row)){
        foreach($row as $id=>$term){
            if(!isset($out[$id])){
                $out[$id] = $term;
            }
        }
    }
}
print_r($out);
