Blowfish encryption, respectively, using PHP and C + + implementation, but the results are different. How to handle

Blowfish encryption, respectively, using PHP and C + + implementation, but the results are different ...
First MD5 experiment, the result is the same, but use Blowfish experiment, how to do also can not succeed
The call is as follows:

 
       
    $cipher = Mcrypt_module_open (Mcrypt_blowfish, ', MCRYPT_MODE_ECB, ');

    $iv   = ' 00000000 ';
    $key  = "Strkey11";

    $stext = ' 38a0e9312dda8f7c16b9a12159168c76 ';
    $stext = MD5 ($stext, true);
    After debugging, you know, at this point the value of $stext is consistent with the result of MD5 in C + +

    if (Mcrypt_generic_init ($cipher, $key, $iv)! =-1)
    {
        $dtext = Mcrypt_generic ($cipher, $stext);
        Mcrypt_generic_deinit ($cipher);

        Display the result in hex.
        printf ("Blowfish Encrypted:
%s

", Strtoupper (Bin2Hex ($dtext)));
    }
    Mcrypt_module_close ($cipher);

C + + is the case:

    Md5_ctx MD5;
    unsigned char str[16];
    MD5. Md5string (STRSOURCE.C_STR (), str);

    Blockcipher *BF;
    Char key[] = "Strkey11";              Key
    BF = new BlowFish ();
    Bf->setkey (void *) key, 8*8);

    Bf->encrypt ((void *) STR, 8);      unsigned char str[16];
    Bf->encrypt (void *) (str+8), 8);
    Char Temp1[4] = {0};
    Char buff1[128] = {0};
    for (int i = 0;i<16;i++)
    {
        sprintf (Temp1, "%02x", Str[i]);
        strcat (BUFF1,TEMP1);
    }
    Ansistring strresult = String (buff1). Uppercase ();
    Delete BF;

------Solution--------------------
$iv = ' 00000000 ';???
Press Bf->setkey (void *) key, 8*8); Understand
Should be
$iv = "\x00\x00\x00\x00\x00\x00\x00\x00";
, huh?

------Solution--------------------
IV is ignored in ECB. IV must exist in CFB, CBC, STREAM, NOFB and OFB modes.
The MCRYPT_MODE_ECB pattern, $iv is ignored, should not be the problem.

It's like padding before encryption, you try.
$size = Mcrypt_get_block_size (Mcrypt_blowfish, MCRYPT_MODE_ECB);
$input = Pkcs5_pad ($input, $size);

function Pkcs5_pad ($text, $blocksize)
{
$pad = $blocksize-(strlen ($text)% $blocksize);
Return $text. Str_repeat (Chr ($pad), $pad);
}

function Pkcs5_unpad ($text)
{
$pad = Ord ($text {strlen ($text)-1});
if ($pad > strlen ($text)) return false;
if (strspn ($text, Chr ($pad), strlen ($text)-$pad)! = $pad) return false;
