Replacing space with "_" when UL a file

As for calling your function, this is the line you should use:
$file=stripspaces($file);

erm...
I use

$dir = opendir($absolute_path);
while($file = readdir($dir)) {
if (($file != "..") and ($file != ".")) {
$file=str_replace(" ","%20",$file);
$list .= "$file"
echo $list;

That gives me full listing og the given folder...

Now I tried to add size ( $size ) of the file right after name of the file ( $file ) by using this script:

// $size is the filesize (in bytes)
function rendersize($size) {

	$type = 'bytes';

	if ($size > '1023') {

		$size = $size/1024;
		$type = 'KB';

	}

	if ($size > '1023') {

		$size = $size/1024;
		$type = 'MB';

	}

	if ($size > '1023') {

		$size = $size/1024;
		$type = 'GB';

	}

	if ($size > '1023') {

		$size = $size/1024;
		$type = 'TB';

	}

	// Fix decimals and stuff
	if ($size < '10') $size = intval($size*100)/100;
	else if ($size < '100') $size = intval($size*10)/10;
	else $size = intval($size);

	// Comment the following line if you want X.XX KB displayed instead of X,XX KB
	$size = str_replace("." , "," , $size);
	return "$size $type";
}

I have NO idea where to insert that script (before html? before head? before ... ?) and what variable to use after that.

I tried some variants like

$list .= "$file $size $type"

but got just empty spaces instead of file size...
I'm sure I'm inserting that script in the wrong place or I have to remove

return "$size $type";

and insert it in other place... I really tried in over 1 hour or so, but couldn't solve this pussle
