Answer 1

Just for fun. If you really want to avoid loops, try this:

// Pre PHP 5.3:

function cb2($e)
{
    return $e['slast'] . ', ' . $e['sfirst'];
}

function cb1($e)
{
    $authors = array_map('cb2', $e['authors']);
    echo implode('; ', $authors) . ":
\n" . $e['sarticle'] . "
\n";
}

array_walk($data, 'cb1');



// PHP 5.3 (untested):

array_walk($data, function($e)
{
    $authors = array_map(function($e)
    {
        return $e['slast'] . ', ' . $e['sfirst'];
    },
    $e['authors']);

    echo implode('; ', $authors) . ":
\n" . $e['sarticle'] . "
\n";
});
