iterate through all the elements in an array instead of print_r

<?php

$filesarray = array();

if ($handle = opendir('.')) {
    while (false !== ($entry = readdir($handle))) {
        if ($entry != "." && $entry != ".." && is_file($entry)) {
            //echo "$entry<br />";
            $filesarray[] = $entry;
        }
    }
    closedir($handle);
}

print_r($filesarray);
?>

Select allOpen in new window

this question is just for the last line:
there are elements in

print_r($filesarray);

and I want to do a foreach or while loop to iterate through all the elements and echo each element
