Keep in mind to have the same encoding for the strings. Try to convert the strings in both languages to UTF-8, e.g., and than convert to binary data that is encoded:

PHP (s. utf8_encode() function):

$strAndBlob = utf8_encode("My string");

Java:

String str = "My string";
byte[] blob = str.getBytes("utf-8");

PHP, e.g., must not use UTF-8 by default.
