Need to translate the same encryption results into 16 binary with PHP

That is, if there are 8 bits such as 00000000
Converted to 16 after encryption is 16 bits

They provide a software I encrypt 12345678
Convert 12345678 with Bin2Hex to 16 binary string result to 3132333435363738
And then encrypt it to get the result of b2a85cf088d9ff03



Now use PHP to implement the same encryption results as it! I tried a lot of times to correspond to, ask the big God paste Code
Java encryption Code is attached:

Thank you!

1 floor own account, online etc.! There are ideas and welcome.

I got it, man. Who are those 100 points?
echo bin2hex (' 88888888 '); exit;

$key = ' 56781234d56f012bcd5e701a3cdd670956781234d56f012b ';
$key = Pack (' H48 ', $key);
echo $key; exit;
$iv = Pack (' h* ', ' 0 ');

function Fmt3desex ($s) {
$key = ' 56781234d56f012bcd5e701a3cdd670956781234d56f012b ';
$key = Pack (' H48 ', $key);
$TD = Mcrypt_module_open (Mcrypt_3des, ', MCRYPT_MODE_CBC, ');
$iv = Pack (' H10 ', "0102030405060708"); Like C # new byte[]{1,2,3,4,5,6,7,8}
$iv = Pack (' H10 ', ' 0000000000000000 ');
Mcrypt_generic_init ($TD, $key, $IV);
$encrypted _data = Mcrypt_generic ($TD, $s);
Mcrypt_generic_deinit ($TD);
Mcrypt_module_close ($TD);
Return Bin2Hex ($encrypted _data);
}

echo fmt3desex (' 88888888 ');

The answer is posted to other skeptical classmates.
