满分求php3des加密的问题 兼容JAVA

3des 对方提供的密钥
56781234D56F012BCD5E701A3CDD6709

需要用PHP和他实现同样的加密 结果转化成16进制

也就是如果有8位 例如 00000000
加密后转化成16进制就是16位

他们提供一个软件 我对12345678 进行加密
先将12345678 用 bin2hex转化成16进制字符串 结果为 3132333435363738
然后进行加密 得到的结果为 B2A85CF088D9FF03
如图：


现在用要PHP实现和它相同的加密结果！我试了很多次都对应不上，求大神贴代码
附JAVA加密代码：

 自己搞定了 我操 这一百分给谁呀  
 //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');
