Laravel Collection - Return 仅值，不需要键

Question

我有一组Laravelcollection，但是我只需要数值，看下面的例子collection，我只需要A1，1.00，我不需要 header 1，header 2...

下面是collection.

{
    header 1: "A1",
    header 2: "1.00",
    header 3: "2020-04-15",
    header 4: "D1 %",
    header 5: "1",
    header 6: "F1",
    header 7: "G1",
    header 8: "H1",
    header 9: "I1",
    header 10: "J1",
    header 11: "K1",
    header 12: "L1",
    header 13: "M1"
},{
    header 1: "A2",
    header 2: "2.00",
    header 3: "2020-04-16",
    header 4: "D2",
    header 5: "2",
    header 6: "F2",
    header 7: "G2",
    header 8: "H2",
    header 9: "I2",
    header 10: "J2",
    header 11: "K2",
    header 12: "L2",
    header 13: "M2"
},

代码如下：

    $collect = $collection->map(function ($rows) {
        return collect($rows)->map(function ($item, $key) {
            return $item;
        });
    });
    return $collect->values()->all();

但是，我总是得到全套 collection，包括 header 1、header 2。

尝试了下面的代码，

$collect = $collection->map(function ($rows) {
        return collect($rows)->map(function ($item) {
            return collect($item)->values();
        });
    });

    return $collect->values()->all();

但是输出如下，

{
header 1: [
"A1"
],
header 2: [
"1.00"
],
header 3: [
"2020-04-15"
],
header 4: [
"D1 %"
],
header 5: [
"1"
],
header 6: [
"F1"
],
header 7: [
"G1"
],
header 8: [
"H1"
],
header 9: [
"I1"
],
header 10: [
"J1"
],
header 11: [
"K1"
],
header 12: [
"L1"
],
header 13: [
"M1"
]
},

Answer 1

这样就可以了:)

$collect = $collection->map(function ($item) {
    return collect($item)->values();
});
return $collect->values()->all();

Answer 2

使用类似下面的内容。

$collect = $collection->map(function ($row) {
     return array_values($row);
});

dd($collect->values()->all());

Answer 3

考虑到您有以下数组

$arrayTbs = [
    [
        'header 1' => "A1",
        'header 2' => "1.00",
        'header 3' => "2020-04-15",
        'header 4' => "D1 %",
        'header 5' => "1",
        'header 6' => "F1",
        'header 7' => "G1",
        'header 8' => "H1",
        'header 9' => "I1",
        'header 10' => "J1",
        'header 11' => "K1",
        'header 12' => "L1",
        'header 13' => "M1"
    ],[
        'header 1' => "A2",
        'header 2' => "2.00",
        'header 3' => "2020-04-16",
        'header 4' => "D2",
        'header 5' => "2",
        'header 6' => "F2",
        'header 7' => "G2",
        'header 8' => "H2",
        'header 9' => "I2",
        'header 10' => "J2",
        'header 11' => "K2",
        'header 12' => "L2",
        'header 13' => "M2"
    ]
];

如果你需要所有的值

$collectionOne = collect($arrayTbs)
        ->map(function($value,$key){
          return collect($value)->values();
        });

如果您需要单个数组中的所有这些值

$collectiontwo = collect($arrayTbs)
        ->map(function($value,$key){
          return collect($value)->values();
        })->collapse();

如果你需要所有的钥匙

$collectionThree = collect($arrayTbs)
        ->map(function($value,$key){
          return collect($value)->keys();
        });

如果您需要单个阵列上的所有这些键

$collectionThree = collect($arrayTbs)
        ->map(function($value,$key){
          return collect($value)->keys();
        })->collapse();
