Php：Laravel - 使用雄辯的拔除方法后的數組推送

Question

這是我的查詢

$RecipientList = Employees::select(DB::Raw('CONCAT(first_name," ",last_name) as employee_name'),'email')->pluck('employee_name','email');

哪能給我正確的結果，

但在執行查詢后，我還有1個key => value對來推送結果數組。

如果我打印當前結果，它是這樣的。

Illuminate\Support\Collection Object
(
    [items:protected] => Array
        (
            [punit@*****.com] => Punit Gajjar
            [milan@*****.com] => Milan Gajjar
            [pritesh@*****.com] => Pritesh Modi
            [pratik@*****.com] => Pratik Modi
            [jyoti@*****.com] => Jyotiranjan J..
        )

)

如果我試圖將我的Key => valye對推入這個數組，那就不行了。

array_push(array("All"=>"All"),$RecipientList);

需要輸出類似的東西

Illuminate\Support\Collection Object
    (
        [items:protected] => Array
            (
                [All] => All
                [milan@*****.com] => Milan Gajjar
                [milan@*****.com] => Milan Gajjar
                [pritesh@*****.com] => Pritesh Modi
                [pratik@*****.com] => Pratik Modi
                [jyoti@*****.com] => Jyotiranjan J..
            )

    )

Answer 1

這是因為$ RecipientList是Collection而不是Array。

試試這個

RecipientList = Employees::select(DB::Raw('CONCAT(first_name," ",last_name) as employee_name'),'email')->pluck('employee_name','email')->toArray();

如果這不起作用，請嘗試以下代碼

RecipientList = Employees::select(DB::Raw('CONCAT(first_name," ",last_name) as employee_name'),'email')->get()->pluck('employee_name','email')->toArray();

希望這會幫助你。

Answer 2

你有Illuminate\\Support\\Collection對象而不是數組。 你可以做

$RecipientList->push(["All"=>"All"]);

UPD：有prepend方法

$RecipientList->prepend('All', 'All');
