opendir works on the filesystem, not on the url, you may need to specify 
the absolute path relative to the filesystem root, or relative to the 
current working directory, which might not be the directory the php file 
is in.

See what value is returned by a call to getcwd() immediately before 
calling opendir.

Also, when using opendir, it's always a good idea to check that the 
result is non false before using it, and handle failures gracefully.

See also http://php.net/manual/en/function.opendir.php

Perhaps it would also be a good idea to wrap your opendir call in an 
is_dir check and handle the case where is_dir is false as well.

"handle" means present a meaningful message to whoever is viewing the 
script output, whether it is a web page or on a console, rather than just 
ignoring the fault condition. Handling may also include some sort of 
logging. See also the handy error_log() function.

http://uk1.php.net/manual/en/function.error-log.php

eg (adapted from the manual example for opendir, not actually tested):

if ( is_dir( $dir ) ) {
    if ( $dh = opendir( $dir ) ) {
            /* search through files */
        }
        closedir( $dh );
    }
    else {
        /* opendir failed */
        error_log( "opendir failed, cwd was '".getcwd()."' and \$dir was 
'{$dir}'",1,"name@example.com" );
        echo "<p>A server error occurred. The system maintainer has been 
notified and will investigate this. Please try again later.</p>";
    }
}
else {
    /* is_dir returned false */
    error_log( "is_dir returned false for '{$dir}', cwd was '".getcwd
()"'",1,"name@example.com" );
    echo "<p>A server error occurred. The system maintainer has been 
notified and will investigate this. Please try again later.</p>";
}
