Sorting in PHP

[Anon]

I'm trying to sort values in php. I realize its very simple to sort in SQL, and it appears simple to sort in php.

I realize the sort function works fine, for example:

<?

$listings = array("joe", "jim", "bob", "dave", "ron");

sort($listings);

echo$listings[3];

?>

But how do I display the results, in alpha listing.

For example, if I had a select box on my web form, how would I put those values in the select box, in alpha order. I'm grabbing the directory names as the values I wish to work with, and I had thought I could loop through the array til no value exists displaying all the names in alpha order in the input box? Am I way off?

Thanks for the help.

"I could loop through the array til no value exists displaying all the names in alpha order in the input box?"
