[php]» alle plaatjes uit dir lezen? - Softwareontwikkeling

Ik ben nieuw met php, en ben bezig met site in (html.
Ik wil daarin een pagina maken waar ik alle foto's in zet. Maar nu zou het natuurlijk fijn zijn als je met php een dir kan uitlezen waar alle plaatjes in staan en ze dan automatisch op de html pagina zetten. Zodat ik alleen maar het plaatje in de dir hoef te uppen, en dat het dan automatisch erbij op de pagina staat.

Heeft iemand zo'n scripie toevallig liggen of kan iemand dat zelf snel in elkaar flansen?

Je zou me er enorm mee helpen.
---------------------------------
Ok ik heb nu een script gevonden, maar wie kan dat script een beetje opschonen? Want dit zou toch korter kunnen??

PHP:

<?
 



require("photogallery-config.php");

if (! $included )
{
    echo "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\">\n";
    echo "<HTML><HEAD><TITLE>Photogallery</TITLE></HEAD><BODY>\n";
}

if (! $number)
    $number = $defnumber;

if (! $pagenum)
    $pagenum = 1;


/* Some helper functions */

function get_pictinfo($picture)
{
    global $infofile;
    # Read the infofile

    $fp=fopen($infofile,"r");
    $contents=fread($fp, filesize($infofile));
    fclose($fp);
    $start = strpos($contents,$picture) + strlen($picture);
    $tmpstr = substr($contents,$start,strlen($contents));
    $stop = strpos($tmpstr, "\n");
    $pictinfo = substr($contents,$start,$stop);

    return $pictinfo;
}

function num2picture($num)
{
    global $thumbdir;
    $othumbdir = dir($thumbdir);
    for($count=0; $count<=($num+1); $count++)
    {
        $entry=$othumbdir->read();
    }
    
    $othumbdir->close;
    return $entry;
}

function picture2num($picture)
{
    global $thumbdir;
    $count = 0;
    
    $othumbdir = dir($thumbdir);

    while($entry=$othumbdir->read())
    {
        $count++;
        if($entry == $picture)
            break;
    }

    return $count - 2;
