创建具有关联数组键和数字数组值的数组PHP [英] Create an array with associative array keys and numeric array values PHP

问题描述

我正在尝试合并两个数组.关联的一个和一个数字数组. $new_array = array_combine($array1, $array2).但这是从数组1中获取值并将其设置为新数组的键，这就是本意.

I am trying to combine two arrays. An associative one and a numeric array. $new_array = array_combine($array1, $array2). But it is taking the values from array one and setting them as the keys for the new array, which is what is meant meant to do.

但是我需要将$ array1的键用作$ new_array的键，将$ array2的值用作$ new_array的值.我还研究了将$ array2的值合并到$ array1中，但是由于数组不共享相同的键，因此无法正常工作.

But I need to use the keys of $array1 to be the keys of $new_array and the values of the $array2 to be the values of the $new_array. I also looked into merging the values of $array2 to $array1 but it does not work properly as the arrays don't share the same keys.

这里是一个例子.

$array1 = "fname" => "NULL", "lname" => "NULL", "id" => "NULL";

$array2 = "john", "smith", "11123";

$new_array = "fname" => "john" , "lname" => "smith", id => "11123";

我正在考虑使用此array_combine(array_flip($array1), $array2);

但是array_flip不能使用NULL;

But array_flip can't work with NULL;

推荐答案

使用 array_flip 像这样:

Use array_keys instead of array_flip like so:

$array1 = ["fname" => "NULL", "lname" => "NULL", "id" => "NULL"];

$array2 = ["john", "smith", "11123"];

$new_array = array_combine(array_keys($array1), $array2);

print_r($new_array);

输出:

Array
(
    [fname] => john
    [lname] => smith
    [id] => 11123
)

演示中的eval.in
