Total Size

[Dysan]

Hi,

 

How do I open a directory using opendir(), loop through the files, and depending on the size of the folder, display the total size in KB, MB, GB, TB etc?

quick google search: http://www.phpit.net/code/list-files-directory/

 

then just use filesize() and divide by your binary increments to get KB, MB, GB, etc.

Could you give me an example, I don't quite understand?

<?php
//from link with modifications
if ($handle = opendir('/path/to/files')) {
    echo "Directory handle: $handle\n";
    echo "Files:\n";

    // List all the files
    while (false !== ($file = readdir($handle))) {
        echo "$file size is: " . filesize($file) . "\n"; //divide filesize by 1024 for kb, 1024^2 for mb, 1024^3 for gb, etc
    }

    closedir($handle);
}
?>

You can also use the function disk_total_space to get the filesize of a folder so you don't need to do all those filesize on all those files.

Can you give me an example of what you mention in your previous most (above) as I have tried it, but I failed to get it working.

Taken from the comments on PHP.net (modified slightly):

<?php
function getSymbolByQuantity($bytes) {
    $symbols = array('B', 'KiB', 'MiB', 'GiB', 'TiB', 'PiB', 'EiB', 'ZiB', 'YiB');
    $exp = $bytes ? floor(log($bytes) / log(1024)) : 0;

    return sprintf('%.2f ' . $symbols[$exp], ($bytes / pow(1024, floor($exp))));
}
?>
