Best way to convert Little-Endian DWORD to string

Hi, Maybe quite strange question and quite off topic, but there's PHP involved :) I want to read out files, and then I come across 4byte DWORD values, they are stored in little endian values, but how do I get in a PHP string (as the values are too large for integer) My code is currently this: $data = fread($fp,4); $value = (ord(substr($data,3,1))*256*256*256)+(ord(substr($data,2,1))*256*256)+(ord(substr($data,1,1))*256)+(ord(substr($data,0,1))); and now $value contains the value of the DWORD, it works fine, but it seems that it could be done a lot easier :) Anyone experience with it?
