Hi,
I've been learning to make classes. I can't seem to figure out why
this code won't work the way I expect. If I use the print statements in
the filez() function of the filez class, it'll do just what I want it to
do.....BUT, when I put the print statements in a separate function
within the class...it gives me an error (Warning: No such index in
string in...). The errors are in the print statement lines. Here's the
code. I have been trying to find info that would help me correct it, but
I cannot. I'm hoping someone on the list can either direct me to the
place that will help, or let me know what I'm doing wrong. I'm at a
complete loss here. Thi is probably a very simple problem, I'm sorry if
it's stupid to ask. I have looked everywhere else I could think of,
before submitting this problem to this list. Thanx..and I appreciate any
feedback.

<?php
class filez {
function filez($folder = ".") {
$lookin = opendir($folder);
while($files[] = readdir($lookin));
sort($files);
for(reset($files); strcmp($key = key($files),""); next($files)) {
if(is_dir($files[$key])) {
$d[] = $files[$key];
} else {
$f[] = $files[$key];
}
}
closedir($lookin);
}
function showit() {
global $d,$f;
print "<h3><a href=\"$d[1]\">$d[1]</a></h3>\n";
print "<a href=\"$f[5]\">$f[5]</a><br>\n";
}
} //end class, and btw this is line #21
?>

<body>
<?php
$w = new filez();
$w -> showit();
?>
