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 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

Answer 1

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;
}

Answer 2

Use glob() plus some filtering for xls files.
glob("*.xls")
