pluck查询字段数
pluck可以同时指定两个字段,以array('key'=>'value')的形式返回,第二个参数为key,第一个为value。貌似不支持三个字段?

只能接受两个参数
public function pluck($column, $key = null)
{
$results = $this->get(is_null($key) ? [$column] : [$column, $key]);
// If the columns are qualified with a table or have an alias, we cannot use
// those directly in the "pluck" operations since the results from the DB
// are only keyed by the column itself. We'll strip the table out here.
return Arr::pluck(
$results,
$this->stripTableForPluck($column),
$this->stripTableForPluck($key)
);
