Help with is_dir

[Anon]

I have a perl script that I use to check for the existence of certain directories on my site. Usually they do not exist. Whenever they do signals a problem. I'm trying to accomplish the same thing in php. I run into an error message when the directory does not exist using is_dir. Is there a better way to go about determining if the directory exists or not?

Here is what I'm using now:

if (is_dir ($lockingdir)) {
    $locked = "Locked";
}
else {
$locked = "Unlocked";
}

and here is what I get:

Warning: stat failed for /mnt/web/guide/mysite/locks (errno=2 - No such file or directory)

Try file_exists($lockingdir);

is_dir just tells you if a file name specified is actually a directory or a real file.
Lazy programmer's way is to put @is_dir($lockingdir). The @ will suppress the error message.
