[PHP]Zmiana nazwy pliku i pobranie go... Opcje

[kuba_pilach]

Witam, próbowałem zmienić nazwę pliku i pobrać go...
O to mój kod:

[PHP] pobierz, plaintext 
rename($name, "plik.sta");
 	//First, see if the file exist
 	if (!is_file($name)) { die("<b>404 File not found!</b>"); }
	//Gather relevent info about file
	$len = filesize($name);
	$filename = basename($name);
	$file_extension = strtolower(substr(strrchr($filename,"."),1));	
	//This will set the Content-Type to the appropriate setting for the file
	switch( $file_extension ) {
		case "sta": $ctype="text/plain";
 
		break;
 
		default: $ctype="text/plain";
	}
	//Begin writing headers
	header("Pragma: public");
	header("Expires: 0");
	header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
	header("Cache-Control: public");
	header("Content-Description: File Transfer");
 
	//Use the switch-generated Content-Type
	header("Content-Type: $ctype");
 
	//Force the download
	@$header="Content-Disposition: attachment; filename=".$filename."";
	header($header);
	header("Content-Transfer-Encoding: binary");
	header("Content-Length: ".$len);
	@readfile($name);
	exit;
[PHP] pobierz, plaintext 

I pisze: File not found.
Wie ktoś, jak to poprawić?
