PHP : Laravel - Array push after using eloquent pluck method

Question

这是我的查询

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

它给我想要的正确结果，

但是在我执行查询之后，我还有 1 个键 => 值对要插入结果数组。

如果我打印当前结果，它是这样的。

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..
        )

)

如果我尝试将我的 Key=>valye 对插入这个数组，它就不起作用。

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

需要输出类似的东西

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

这是因为 $RecipientList 是集合而不是数组。

试试这个

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

如果不行，试试下面的代码

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

希望对您有所帮助。
