how to get the filesize of all the files in a folder!

[MJB3K]

Hi, how would you open a folder, then get the filesize for each file, add them together and then display the total file size??

any ideas??

If you are in a *NIX type OS you could also use the system specific du function in an exec() statement.

1: Find a VERY simple dirlist script
2: In the loop, add a line:

$total = filesize($the_variable_that_contains_file);

3: parse it out

ps. you might need to run clearstatcache() before each time you run the filesize(), as the results of filesize() are cached!

For the simple dirlist script, look here:

I guess it's your lucky day.. I was a bit bored now, so I made it for you..

<?php
$dir = "./";

echo "<table width=\"100%\">
<tr><td>Filename</td><td>FileSize</td><td>Filetype</td></tr>
<tr><td colspan=\"3\"><hr /></td></tr>
";
// Open a known directory, and proceed to read its contents
if (is_dir($dir)) {
   if ($dh = opendir($dir)) {
       while (($file = readdir($dh)) !== false) {
           $fsize = filesize($dir . $file); // get filesize
           echo "<tr><td>{$file}</td><td>{$fsize}</td><td>" . filetype($dir . $file) . "</td></tr>\n";
          $numfiles++;
          $sum_kb += $fsize;
        clearstatcache(); // clear cache about files..
       }
       closedir($dh);
       echo "<tr><td colspan=\"3\"><hr />Total filesize: {$sum_kb}<br />Number of files: {$numfiles}</td></tr>
                </table>";
   }
}
?>

ps. you might want to do something with the way filesize is displayed. I hardly think anyone wants to see it in kb.. unless you specify that your users can only upload 512kb or something like that though.

bare in mind that 1mb = 1024kb, not 1000..
This is why you dont get 250gb out of a 250gb harddrive. it's actually ((250 * 1000) * (1 / 1.024)) / 1000
results in 244GB 140MB and 625KB
