Description:
------------
In the PHP 5.3,packing and unpacking function is done like Perl,
but like in Perl processing for 64 bit data is missing.Hence  Implemented it and tested it, the source code as follows 
http://www.gnudeveloper.com/software/php-5.3/pack.c

The PHP example code also found at      

http://www.gnudeveloper.com/forum/viewtopic.php?f=4&t=11&p=27#p27
 
  


Reproduce code:
---------------
$vBinData = pack("Q", 0x1234567812345678);
$vHexData = bin2hex($vBinData);
var_dump($vHexData);

list(,$v32Value) = unpack('Q', chr(0x80).chr(0x00).chr(0x00).chr(0x00).chr(0x00).chr(0x00).chr(0x00).chr(0x09));
print $v32Value.'<br>'."\n";
echo hexdec(dechex($v32Value)) . "0x" . dechex($v32Value) . "<br>";
