php – How to combine two arrays together?

Posted by: admin July 12, 2020 Leave a comment

Questions:

Is there a quick way to combine one arrays values as the other array’s keys?

Input:

array A => Array (
        [0] => "cat"
        [1] => "bat"
        [2] => "hat"
        [3] => "mat"
    )

array B => Array (
        [0] => "fur"
        [1] => "ball"
        [2] => "clothes"
        [3] => "home"
    )

Expected output:

array C => Array (
        [cat] => "fur"
        [bat] => "ball"
        [hat] => "clothes"
        [mat] => "home"
    )

How could I do that?

How to&Answers:

array_combine() will exactly do what you want.

Quoting the manual:

array array_combine ( array $keys , array $values )

Creates an array by using the values from the keys array as keys and the values from the values array as the corresponding values.

In your case, you’d have to do something like this:

$array['C'] = array_combine($array['A'], $array['B']);

While of course you could also use various combinations of loops to do that, array_combine() is probably the simplest solution.

Answer:

You can do this simply with array_combine:

// First parameter will be used as the keys, the second for the values
$new_array = array_combine($keys_array, $values_array);

Answer:

Try this: array_combine($a, $b);
