pluck查詢字段數(shù)

pluck可以同時指定兩個字段，以array('key'=>'value')的形式返回，第二個參數(shù)為key,第一個為value。貌似不支持三個字段？

只能接受兩個參數(shù)

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)
????????);
????}
