Simple array question

[mstembri]

while ($file = readdir($dir))  { 
    if (($file != ".") && ($file != ".."))  {
        $fname = "$dir_name/$file";
        $ftime = filectime($fname); 
        $fsize = filesize($fname); 
        $ftime = date("m/d/Y G:i", $ftime); 
        $x = "|";
        $key[] = $ftime . $x . $file . $x . $fsize;
    } 
} 
arsort($key);
for($t=0; $t < $countfiles; $t++)  { 
    $listfile = each($key); 
    $listfile = explode("|", $listfile);
    $listfilename = $listfile[0]; 
    $listfiletime = $listfile[1]; 
    $listfilesize = $listfile[2]; 
    echo"<b>$listfilename</b> -  $listfiletime -  $listfilesize<br>";
} 

This script returns a list of 34 lines saying "Array".

If I comment out

$listfile = explode("|", $listfile); 

the script prints out each value of $key (not usable).

I've been back to php.net looking over the array page... I geuss I'm being very dense today, but I still don't understand arrays in the context of this script. Clarification, I know what an array is, I'm just having a little trouble getting this to work.

Okay so I looked over your code, but I think you are making this entirely too hard and a little inefficient. I would use a multi-dimensional array instead of a pipe-delimited string. That way you save yourself the time to split the string up and such. This should work a littl faster.

<?
$base_dir = "uploads/";
$dir = opendir($base_dir);
while ($file = readdir($dir))  { 
    if (($file != ".") && ($file != ".."))  {
        $files[] = array("fname" => $file, 
                         "ftime" => date("m/d/Y G:i", filectime($base_dir.$file)), 
                         "fsize" => filesize($base_dir.$file)
                         );
        }
} 
arsort($files);
foreach($files as $key => $file) {
    echo "<b>", $files[$key]['fname'], "</b> -  ", $files[$key]['ftime'], " -  ", $files[$key]['fsize'], "<br>";
    }

?>

That was what I thought I should do at first, but after a few days of no success I started trying other methods.

The good news is that the files are printing to the screen, but I am a little confused by the output...

     somefile.jpg - 12/31/1969 19:00 -

The date is the same on all the files, plus the size somehow isn't printing out.

I thouhgt that it might be that we were processing the date twice, but I can only see where it is being run through date once.

Thanks for the help/guidance.

I was having the same probl;em, its because you need to reference that filectime() and filesize() on real files with a correct path. Thats why I added the $base_dir var in there. But you may want to play with that part of it, as its the only part that is not working properly.

In your script, you assign $fname the value of $dir_name/$file so now you have a full path and filename to work with. In mine I did not do that and instead assigned a value to $base_dir and tacked that onto the front of each one. So you'll need to either adjust $base_dir to be a real path on your system, or change how that var works.

But the code works fine, at least on my machine.

I changed $base_dir = 'uploads/' to

$base_dir = 'C:/wwwroot/uploads/';

It had no effect on the script, but I think an absolute path will probably solve your problem, as for me uploads/ is relative path to where the script lives, so thats why it worked for me.

Simple fix, it works fine now. And I think I have a little better understanding of the process.
