Visualizzare elenco file PDF

[marckj]

Salve a tutti,
premetto che con il php ho problei

Sarò breve:

vorrei creare una pagina in php che visualizza un elenco di file PDF contenuti in una cartella,
l'elenco deve semplicemente una lista con il nome del file ed il logo in pdf,
se il file esiste lo visualizza altrimenti no ( ) poi ad ogni nome deve corrispondere il link
per il download del file.

NON posso usare MySQL

Domanda:
Come posso fare???

Ho iniziato a scrivere questo ma non credo sia corretto.!!!
<?php
$fs = "CARTELLA_CONTENENTE_FILE_PDF"; -----> mi serve del cdice per identificare la presenza del file pdf ed il nome
$fb = "prova.pdf";
if( file_exists( $fs ) )
echo 'NOME_DEL_FILE';
?>
