如何创建一个新的键名并将数组中的值与PHP组合？

Question

I have 2 PHP arrays that I need to combine values together.

First Array

array(2) {
    [0]=>
    array(1) {
        ["id"]=>
        string(1) "1"
    }
    [1]=>
    array(1) {
        ["id"]=>
        string(2) "40"
    }
}

Second Array

array(2) {
    [0]=>
    string(4) "1008"
    [1]=>
    string(1) "4"
}

Output desired

array(2) {
    [0]=>
    array(1) {
        ["id"]=>
        string(1) "1",
        ["count"]=>
        string(1) "1008"
    }
    [1]=>
    array(1) {
        ["id"]=>
        string(2) "40",
        ["count"]=>
        string(1) "4"
    }
}

As you can see I need to add a new key name (count) to my second array and combine values to my first array.

What can I do to output this array combined?

Answer 1

Try something like the following. The idea is to iterate on the first array and for each array index add a new key "count" that holds the value contained on the same index of the second array.

$array1 = [];
$array2 = [];

for ($i = 0; $i < count($array1); $i++) {
    $array1[$i]['count'] = $array2[$i];
}
