PHP list all files in directory

ive got a cron job running creating .xls files every 24hrs, they are creating them in a directory on my site called http://www.mysite.com/sheets

what i want to do is make a webpage where i can go to and see all the .xls files in that directory and download the ones i was instead of having to download them using an ftp client.

Is there a name for this sort of thing ? what would i write it in ? i was thinking i could do it in php by echoing the folders contents, would that work ?

cheers

You could activate directory listing within your webserver, or you can use a function like glob(“*.xls”) to list the files and echo their path on the webserver or you can send a file to the browser like this:

<?php
$filename = "path/to/your/file.xls";
$real_filename = "file.xls";
header('Content-Transfer-Encoding: none');
header('Content-Type: application/octet-stream; name="' . $real_filename . '"');    
header('Content-Disposition: attachment; filename=' . $real_filename);                
$size = @filesize($filename);
if ($size > 0) {
    header('Content-length: '.$size);
} else {
    header('Content-length: '.@strlen(@file_get_contents($filename)));
}
readfile($filename);
exit;
?>

If you want to list a directory use this:

$handle = opendir("./");
while (false !== ($file = readdir($handle))) {
    $fileinfo = pathinfo($file);
    if (strtolower($fileinfo[extension]) == "xls") {
        echo $file;    
    }
}
closedir($handle);

Or this:

foreach (glob("*.[xX][lL][sS]") as $filename) {
    echo $filename;
}
