Remove trailing blank lines at the end of a file

Hello to all,
I'm far from being an expert of PHP, but I'm fighting with a light
procedure to remove trailing blank lines at the end of a file I've in
input from a user.

I'm using this code, but the lines containing a space and a \n at the
end, still remain :-(

$search = array(" ","\r\n","\r","\t","\n");
$replace = "";
$userfile = str_replace($search, $replace, $userfile);
$userfile=preg_replace("/^\n*$/","",$userfile);

//$userfile still has trailing blank lines at the end of file. Why?

many thanks!

Luk

Because you're not using trim().

$userfile holds the *contents* and not the *name* of the file, right?
Right??

You are writing the trimmed stuff back to the file, right?

Yes, should be. This is the code used:

if (move_uploaded_file($_FILES['uploaded_file']['tmp_name'],
$userfile)) {
echo 'OK';
}

then after the checks about the spaces and other chars, there's the
foreach cicle that works:

$lines =3D file($userfile);
show/hide quoted text
//stuff
}
