如何使用PHP删除外部数组

Question

Currently I am getting the following output

Array
(
    [0] => Array
    (
        [name] => car
    )

    [1] => Array
    (
        [name] => bike
    )

)

what I need is:

Array
(
    [0] => car
    [1] => bike
)

What I have tried:

print_r(reset($get_vehicle_names));
print_r(current($get_vehicle_names));

foreach($get_vehicle_names as $key => $value)
{
    $newArr[$key] = $value;             
}

but it doesn't seem to be working

Just use array_column, you will get what you want.

$arr = array(
        array("name" => "car"),
        array("name" => "bike")
    );
$arr_output = array_column($arr, 'name');

echo '<pre>';
print_r($arr_output);

Result:

Array
(
    [0] => car
    [1] => bike
)
