Convert Java code to PHP codebase.

I need to convert the below code from Java, to PHP. public static final String MakeHexStr(byte[] byteArr) { ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); PrintStream printStream = new PrintStream(byteArrayOutputStream); for (byte valueOf : byteArr) { [login to view URL]("%02X", new Object[]{[login to view URL](valueOf)}); } return [login to view URL](); }
