Interesting solution. array_map with a callback makes my head spin a
bit! I'll try to benchmark this solution versus foreach to see which is
faster and will report back.

I'm not 100% clear on what you're looking to do, but this might be an
alternative to a foreach if your intention is to get the value of every
"name" for each index:

    $records =  array(
        array ('name'=>'foo', 'junk'=>'asdf'),
        array ('name'=>'bar', 'junk'=>'asdf'),
        );
    function get_name($array) { return $array['name']; }
    $names = implode(', ', array_map('get_name', $records));
    // $names is 'foo, bar'

HTH,
Andrew
