如何使用collection合并laravel中的数组，使一个成为key？

Question

我有一个这样的数组：

array (
array("Delhi", 22, "The capital of India"), 
array("Varanasi", 23, "Oldest Living City"), 
array ("Moscow", 24, "Capital of Russia"), 
array ("Konya", 25, "The city of Rumi"), 
array("Salzburg", 26, "The city of Mozart")
);

我想像这样创建一个关联集合：

['city' => "Delhi",
'id' => 22,
'description' => "The capital of India"
], 
['city' => "Varanasi",
'id' => 23,
'description' => "Oldest Living City"
], 
['city' => "Moscow",
'id' => 24,
'description' => "Captial of Russia"
]

这可以通过循环传递数据来完成，但集合中是否有任何东西可以完成此操作？

可以使用 array_combine 或结合 Laravel

$collection = array(
    array("Delhi", 22, "The capital of India"),
    array("Varanasi", 23, "Oldest Living City"),
    array("Moscow", 24, "Capital of Russia"),
    array("Konya", 25, "The city of Rumi"),
    array("Salzburg", 26, "The city of Mozart")
);


array_map(function($array){
    return array_combine(['city', 'id', 'description'], $array);
}, $collection);

//Or with a Laravel collection
collect($collection)->map(function($arr){
    return array_combine(['city', 'id', 'description'], $arr);
});
