PHP/Laravel - Create an array of objects from two simple arrays or an associative array that combines that two
提问by Matt Larson
I'm looking for a way transform a php associative array into an array of object and keying each association. I could also treat this as two separate simple arrays, one with the names and one with the classes. Here's an associative example...
我正在寻找一种将 php 关联数组转换为对象数组并键入每个关联的方法。我也可以将其视为两个单独的简单数组，一个带有名称，另一个带有类。这是一个关联的例子......
array:2 [
"someName" => "someClass"
"someOtherName" => "someOtherClass"
]
Or
或者
names => [0 => 'name1', 1 => 'name2']
classes => [0 => 'class1', 1 => 'class2']
...either way, I'm looking for an end result like this:
...无论哪种方式，我都在寻找这样的最终结果：
[
{ 'name': 'someName', 'class': 'someClass' },
{ 'name': 'someOtherName', 'class': 'someOtherClass' }
]
What's the smartest way to do this?
做到这一点最聪明的方法是什么？

I think the best way is to combine zipmethod with transformor map:
我认为最好的方法是将zip方法与transform或map结合起来：
$names = [0 => 'name1', 1 => 'name2'];
$classes = [0 => 'class1', 1 => 'class2'];
$merged = collect($names)->zip($classes)->transform(function ($values) {
return [
'name' => $values[0],
'class' => $values[1],
];
});
dd($merged->all());
As a result you get array:
结果你得到数组：
array:2 [▼
0 => array:2 [▼
"name" => "name1"
"class" => "class1"
]
1 => array:2 [▼
"name" => "name2"
"class" => "class2"
]
]
so if you need json, you can just use json_encode($merged)
所以如果你需要json，你可以使用 json_encode($merged)

This output is the same on your first block.
这个输出在你的第一个块上是一样的。
$array = ['someName' => 'someClass', 'someOtherName' => 'someOtherClass'];
You can also use laravel collections, provides a fluent, convenient wrapper for working with arrays of data. For example, check out the following code.
您还可以使用 laravel 集合，它为处理数据数组提供了流畅、方便的包装器。例如，查看以下代码。
$collection = collect([
'names' => [
['0' => 'name1', '1' => 'name2'],
],
'classes' => [
['0' => 'class1', '2' => 'class2']
],
]);
There is also method combine that your looking for, The combinemethod combines the values of the collection, as keys, with the values of another array or collection: Read more info at https://laravel.com/docs/5.7/collections
还有您正在寻找的combine方法组合，该方法将集合的值作为键与另一个数组或集合的值相结合：在https://laravel.com/docs/5.7/collections阅读更多信息
