Using PHP look through a directory of files and filter by 3-digit number

I need to be able to sort through a list of files that have a naming scheme like this.
example:
102.101_floorplan.pdf
102.105_floorplan.pdf
103.105_floorplan.pdf
etc.,.......

what is the easiest way to search through this list. Using the first 3-digit number, get the file names and output a link for download on my web page. I would need to filter the results so that if there were 10 floorplans for one property or 2 floorplans for another it wouldn't matter. It would just output what was filtered through. Any help is appreciated greatly.

Can go like this. Place the code in the file floor and directory where the pdf are stored and give the search as parameter id to get the list.

http://x/pdf/floors.php?id=101
$searchnumber = '101';
$searchnumber = $_GET['id'];
$dir = '.';
if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            if (substr($file,0,3) !== $searchnumber) {
                continue;
            }
            echo "<a href=\"$file\">$file</a>\n";
        }
        closedir($dh);
    }
}

The variable that I'm passing from page to page is:
PropNum=101 the url looks like this "infosheet.php?PropNum=101"

Can this variable be placed into the $searchnumber variable and the script run from that?

Yes replace
$searchnumber = $_GET['id'];
with
$searchnumber = $_GET['PropNum'];


$searchnumber = '101';
can be ignored, only used for internal testing
