仅使用本机PHP函数从数组中的列表数组中获取数组值

Question

I have an array below:

$arr = array(
    array(
        'name' => 'ABC'
    ),
    array(
        'name' => 'CDF'
    ),
    array(
        'name' => 'GHI'
    )
)

How can I convert to just with native function in PHP:

$arr = array( 'ABC', 'CDF', 'GHI');

Answer 1

$arr = array_map('current', $arr);
