从常规数组中创建具有相等键和值的assoc数组 [英] Create an assoc array with equal keys and values from a regular array

问题描述

我有一个看起来像

$numbers = array('first', 'second', 'third');

我想有一个函数，它将这个数组作为输入并返回一个看起来像这样的数组:

I want to have a function that will take this array as input and return an array that would look like:

array(
'first' => 'first',
'second' => 'second',
'third' => 'third'
)

我想知道是否可以使用array_walk_recursive或类似的东西...

I wonder if it is possible to use array_walk_recursive or something similar...

推荐答案

您可以使用 array_combine 函数，如下所示:

You can use the array_combine function, like so:

$numbers = array('first', 'second', 'third');
$result = array_combine($numbers, $numbers);
