Some newby array help

[zscott]

Using scandir, following along the online docs, and I end up with something like..

Array(	[0] => .	[1] => ..	[2] => bar.php	[3] => foo.txt	[4] => somedir)

How could I output this array into some html, maybe a UL.. foreeach?

for($i=0;$i<sizeof($arr);$i++){  echo $arr[$i] . "<br>";}

or

foreach($arr as $key){  echo $key . "<br>";}
