easy function to convert hexdata to bindata. It's very good to use decode mcrypt hexdata.

<?php
function hex2bin($source)

                              {

                              $strlen = strlen($source);

                              for ($i=0;$i<strlen($source);$i=$i+2)

                                {

                                $bin .= chr(hexdec(substr ($source, $i,2)));

                                }

                              return $bin;

                              }
?>

Usage Example

$hexdata="FFF0A025ef";

                            $bindata = hex2bin($hexdata);
