unzip a file - destination folder wrong

Hi there, I am trying to unzip a zip file. Therefore I am using this function: # unzip a file function extract_zipfile($filename){ $zip = zip_open($filename); if ($zip) { while ($zip_entry = zip_read($zip)) {

	    $fp = fopen(zip_entry_name($zip_entry), "w");
	    if (zip_entry_open($zip, $zip_entry, "r")) {
	      $buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry));
	      fwrite($fp,"$buf");
	      zip_entry_close($zip_entry);
	      fclose($fp);
	    }

} zip_close($zip); } } It works, but unfortunatelly the extracted files are all placed into the directory where the php file is located. Not where the original zip file was found. I tried to add the directory to fwrite, but without success. Does somebody know where to specify the target directory? Thank you for any help, Merlin
