Answer

Using foreach loop without key

foreach($array as $item) {
    echo $item['filename'];
    echo $item['filepath'];

    // to know what's in $item
    echo '<pre>'; var_dump($item);
}

Using foreach loop with key

foreach($array as $i => $item) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];

    // $array[$i] is same as $item
}

Using for loop

for ($i = 0; $i < count($array); $i++) {
    echo $array[$i]['filename'];
    echo $array[$i]['filepath'];
}

var_dump is a really useful function to get a snapshot of an array or object.
