Listing Files...

pyro

I'm using this code to list all the files that are in a certain directory.

<?PHP
$Open = opendir ("directory");
while ($Files = readdir ($Open))
{
	$Filename = $uploaddir . $Files;
	if (is_file ($Filename))
	{
		$Size = filesize ("directory/$Files");
		print ("$Files&nbsp;$Size<br>");
	}
}
closedir ($Open);
?>

The problem is it doesn't list all the files. It will only list two of them...

If I use this

<?PHP
$Open = opendir ("directory");
while ($Files = readdir ($Open))
{
	$Size = filesize ("directory/$Files");
	print ("$Files&nbsp;$Size<br>");
}
closedir ($Open);
?>

It list all the files, the directories, and .4096 and ..4096 (I'm assuming that the last two are refresh and up one level?) Anyway, does anyone know how I can list the files in a certain directory?

Shouldn't $uploaddir be "directory" instead? Otherwise is_file will always return false because you're giving it the wrong path to the file.

Yes, I just noticed that myself. It's working now. Thanks.

Ok, another question. Is there a way to list all the directories, without listing the .4096 and ..4096?

acidbox

you could add an IF statement inside the while statement.

use the substr function to find out which directories start with a . and then exclude them.

pyro

Thanks for your reply, I had done something like that and it is working, so that's a good thing... 🙂

I've got the exact same code to list subfolders but for some reason it doesn't list them alphabetically which seems kinda weird to me cos every other time I've listed folders in whatever language they always come out in the right order.

I kinda need them to so any help would be cool.

Cheers!

They are sorted by created time. If you want to sort them by name, use the sort() function.

Right, I see. Cheers m8!

<?PHP
$Open = opendir ("directory");
while ($Files = readdir ($Open))
{
	$Filename = $uploaddir . $Files;
	if (is_file ($Filename))
	{
		$Size = filesize ("directory/$Files");
		print ("$Files&nbsp;$Size<br>");
	}
}
closedir ($Open);
?>

Just some FYI, while this does work, I've read in several places (the PHP manual being one of them) to use:

while(false !== ($Files = readdir($Open)))

instead of what you have. Just thought I'd let you know.

Thora_Fan is correct http://www.php.net/manual/en/function.readdir.php
I've taken the script from that page and modified it to do the same thing.

<?php 
$folder = "directory";

if ($handle = opendir($folder)) {
    while (false !== ($file = readdir($handle))) { 
        if (is_file("$folder/$file")) { 
            $size = filesize("$folder/$file");
            echo "$file $size<br>\n"; 
        } 
    }
    closedir($handle); 
}
?>

Ok, I've changed my script to

while (false !==($file = readdir($handle))) { $array[] = $file; }

The extra stuff at the end is just more things that I've been working on. Thanks.
