You can use array_column (http://php.net/manual/en/function.array-column.php) as follows:

$records = array(
    array(
        'friendId' => 107,
    ),
    array(
        'friendId' => 103,
    ),
    array(
        'friendId' => 131,
    )
);

$friendId = array_column($records, 'friendId');
print_r($friendId );

try once

function myfunction($v) {
    return($v['friendId']); 
}

$a = array(
    array('friendId' => 107),
    array('friendId' => 103),
    array('friendId' => 131)
);
print_r(array_map("myfunction",$a));
