Getting subdirectory contents with PHP4

how to go about returning the contents of a given directory.

Uh; I've been tasked with the monumental task of making a website more dynamic and useful; one of the things I'm required to do is create a php script that will read the contents of a subdirectory, so we can simply plonk reports and papers and whatnot in the subdir and have them viewable.
Currently, I've only got as far as listing the current directory - the one the script resides in.

//code begins
$getdir = dir(".");
print("<UL style='text-align: left;'>\n");
while($entry = $getdir->read())
 {
if ($entry!= "." && $entry!= ".." && $entry!= "index.php" && $entry!= "default.php")
{ print("<LI><a href=$entry>$entry \n</a>"); }
 }

this is the code I'm using, it was shamelessly tea-leafed from some php site, though I can't find it again. Anyway, the PHP manual seems to imply that I can set dir("/etc"); and have it list the contents of that tree, but doing so brings up:
Fatal error: Call to a member function on a non-object in path to htdocs/user on line 25.
[25 in the fully formatted script is the while statement]

Can anyone begin to shed some light on it? (should I be using readdir? etc)

Cheers.

Figured it out. It was simple, really. I was trying to list /folder when I should've been trying to list the absolute one that the error reports, which is something like users/www/random-number/string/htdocs.

One problem down, millions more to go.

Alrighty, related issue. I need to filter out certain filetypes, or filter in only certain filetypes, it amounts to the same. Only I don't know where to begin. I'd like only .html/htm files to be displayed within the above script. I've looked at the if $entry!=Ideally, I'd like to be able to print the filesizes too, but thats less of an issue. I'm off to read more of the PHP manual :\

you could use either the strstr or stristr functions (in the strings function category) or use the *reg functions in the Regexp function list (see php.net documentation). I would favor using the regular expression functions, but that's because I started in Perl and use regexp often. If you are a beginner it may be easier to use the strstr and stristr functions.

what about using an array and then count .htm occurences. It should be only one really but will also trap .html.

$checkarr = array(".","..","index.php","default.php");
if (!in_array($entry,$checkarr) && substr_count ($entry,".htm") >= 1)
print("<LI><a href=$entry>$entry \n</a>");
