java版MD5轉換成php版

java代碼

public static String encryptMD5_Salt(String content) {    String resultString = "";    String appkey = "acdf,kef";    byte[] a = appkey.getBytes();    byte[] datSource = content.getBytes();    byte[] b = new byte[a.length + 4 + datSource.length];    int i;    for (i = 0; i < datSource.length; i++) {        b[i] = datSource[i];    }    b[i++] = (byte) 143;    b[i++] = (byte) 112;    b[i++] = (byte) 131;    b[i++] = (byte) 143;    for (int k = 0; k < a.length; k++) {        b[i] = a[k];        i++;    }    try {        MessageDigest md5 = MessageDigest.getInstance("MD5");        md5.update(b);        resultString = new HexBinaryAdapter().marshal(md5.digest());    } catch (Exception e) {        e.printStackTrace();    }    return resultString.toLowerCase();}

php代碼:

function javaMd5($data) {   assert(is_array($data));   $dataString = byteArrayToString($data);   $hashString = md5($dataString);   return $hashString;}function byteArrayToString($b) {   assert(is_array($b));   $asciiString = '';   for ($i = 0; $i < count($b); $i++) {      $asciiString .= chr($b[$i]);   }   return $asciiString;}$re=array_merge   (unpack("c*", pack("a*", $content)),   pack("c", pack("l", 143)),   unpack("c", pack("l", 112)),   unpack("c", pack("l", 131)),   unpack("c", pack("l", 143)),   unpack("c*", pack("a*", "acdf,kef"))   );$re = javaMd5($re);
