file size conversion function/class

[searain]

Hi, I am looking for a class or function. It is simple but I would like to use a standard clean one instead of write one of my own.

This class or function should get the input value as float and return as the following:

Say if the input size is 890. then it will still be 890.

but if it is 1026, it should return 1 KB.

And if it is 2,000,000, it should return 2 MB.

C'mon, you can write one of those. It's very simple. But, if time is a constraint, hunt around the 'net script archives. You're bound to find one.

a perfect good one in php.net filesize() chapter. this first place I should look for. 🙂

function fsize($file) {

// Does the file exist?
if(is_file($imagedir.$file)){

    //Setup some common file size measurements.
    $kb=1024;
    $mb=1048576;
    $gb=1073741824;
    $tb=1099511627776;

    //Get the file size in bytes.
    $size = filesize($file);

    //Format file size

    if($size < $kb) {
    return $size." B";
    }
    else if($size < $mb) {
    return round($size/$kb,2)." KB";
    }
    else if($size < $gb) {
    return round($size/$mb,2)." MB";
    }
    else if($size < $tb) {
    return round($size/$gb,2)." GB";
    }
    else {
    return round($size/$tb,2)." TB";
    }
}

}
?>

ACtually depends on your database/table character set up, the sort order is case sensitive

ORDER BY email

will be A B C D ... Z a b c ... z

So Z will be before a
