php - 将值设置为数组中的索引

Question

This is my array:

Array
(
    [0] => Array
        (
            [0] => Q1
            [1] => 100
        )

    [1] => Array
        (
            [0] => Q2
            [1] => 200
        )

    [2] => Array
        (
            [0] => Q3
            [1] => 300
        )

)

I want to have an array like this:

Array
 (
[Q1] => 100
[Q2] => 200
[Q3] => 300
)

So basically I want to split all arrays in one, and 0 key of all multi arrays will be key in the new array and 1 value in multi-array will be value in the new array. I tried with array_combine, but that does not work for me, any ideas?

There's a function for that:

$result = array_column($array, 1, 0);

Failing that just loop:

foreach($array as $v) { $result[$v[0]] = $v[1]; }
