Unlinking?

[Anon]

here's my code:

$d = dir("/usr/local/plesk/apache/vhosts/flexmo.com/httpdocs/inc");
$cow = "/usr/local/plesk/apache/vhosts/flexmo.com/httpdocs/inc/";
$delete = $delete + ".txt";

while($entry=$d->read()) {
if ($entry == $delete)
{
unlink("$cow$entry");
}
}
$d->close();

I'm basically trying to match up the user input to the entries in the directory. I get this error:

Warning: Unlink failed (Permission denied) in /usr/local/plesk/apache/vhosts/flexmo.com/httpdocs/test2/delete.php on line 10

Warning: Unlink failed (Is a directory) in /usr/local/plesk/apache/vhosts/flexmo.com/httpdocs/test2/delete.php on line 10

Please help if you can.

i would guess your permissions for the file are not set to where PHP has access to delete the file. And you cannot use unlink to remove a directory. The second error may come from $entry not being set and then it is trying to unlink $cow which would be a directory.

the permissions are set $cow and $entry together create /usr/local/plesk/apache/vhosts/flexmo.com/httpdocs/inc/example.txt

I'm still not sure how this si throwing me off
