Create array from nested array with php

Question

Is it possible to create array like that:

Array
        (
            [Name] => John
            [Last Name] => Doe
            [Age] => 19
        )

from nested array like that:

    [1] => Array
        (
            [Name] => John
        )

    [2] => Array
        (
            [Last name] => Doe 
        )

    [3] => Array
        (
            [Age] => 19
        )

Nested array is created when adding values in array while making a loop

foreach ($users as $user) {
        $users[] = array($user['title'] => $user['value']);
    }

Answer 1

More simplified @NigelRen's solution is using array_column :

$output = array_column($users, 'value', 'title');

Answer 2

You should change the way the array is built rather than process it further. You are currently adding new arrays each time...

$output = [];
foreach ($users as $user) {
    $output[$user['title']] = $user['value'];
}

Answer 3

You could use array_walk_recursive it will also work if you have nested array

array_walk_recursive($a, function($v, $k) use (&$new){ $new[$k]=$v;});

Answer 4

You can use array_reduce

$result = array_reduce(array(
    array("Name"=>"John"),
    array("Last Name" => "Doe"),
    array("Age" => 19)
),function($a,$b){return array_merge($a,$b);},[]);
print_r($result);
