[Resolved] Division - Am I crazy?

[felipe_lopes]

Plz guys, help me free my mind...

I have this function:

<?php 
function size($dir) { 

$size    =    0; 

if(is_dir($dir)) { 
    $handle    =    opendir($dir); 

    while (($file = readdir($handle)) != false) { 

        if (($file != ".") && ($file != "..")) { 
            if (is_dir($dir."/".$file)) { 
                $size    +=    size($dir."/".$file); 
            } 

            if (is_file($dir."/".$file)) { 
                $size    += filesize($dir."/".$file); 
            } 
        } 
    } 
    closedir($handle); 
} 
else { 
    $size    += filesize($dir);

}

return $size;
}

//just to see if works
echo size("./");
?>

All right....Echos the total bytes of current directory...But, I want to divide the result by 1024 to get the results in kb:

<?php 
function size($dir) { 

$size    =    0; 

if(is_dir($dir)) { 
    $handle    =    opendir($dir); 

    while (($file = readdir($handle)) != false) { 

        if (($file != ".") && ($file != "..")) { 
            if (is_dir($dir."/".$file)) { 
                $size    +=    size($dir."/".$file); 
            } 

            if (is_file($dir."/".$file)) { 
                $size    += filesize($dir."/".$file); 
            } 
        } 
    } 
    closedir($handle); 
} 
else { 
    $size    += filesize($dir);

}

//line added
$size /= 1024;

return $size;
}

echo size("./");
?>

Looks perfect for me, but when I run the script it returns me a crazy number, which is not the size of directory in Kb...

What's going on here??

Thanx in advance

Do you mean that it gives you too exact information? If thats the case, you can round it up using ceil() or floor() function.

return floor($size);

Nope!

I mean that it should returns me 102 kb and it returns 17.434 kb...

I get the number in bytes from the first function (w/out the KB stuff)...Then I divide it manualy (calculator) by 1024 and it gives me 102 kb ... If I run the second function, which should returns me 102 as well, it returns me 17!!!

Damn function called itself...Resolved now...
