"mbstring" Basic Tests

I wrote the following script to test some of the "mbstring" basic functions, MbStringBasic.php:

   print("\nCurrent settings:\n");
   $settings = mb_get_info();
   foreach ($settings as $k => $v) {
      print "   $k = ($v)\n";
   }

   print("\nEncoding detection:\n");
   $str = "Hello!";
   $coding = mb_detect_encoding($str);
   print("1. ".$coding." for (\x".bin2hex($str).")\n");

   $str = "\x00H\x00e\x00l\x00l\x00o\x00!";
   $coding = mb_detect_encoding($str);
   print("2. ".$coding." for (\x".bin2hex($str).")\n");

   $str = "\xC2\xA1Hola!";
   $coding = mb_detect_encoding($str);
   print("3. ".$coding." for (\x".bin2hex($str).")\n");

   $str = "\xE4\xBD\xA0\xE5\xA5\xBD!";
   $coding = mb_detect_encoding($str);
   print("4. ".$coding." for (\x".bin2hex($str).")\n");

   $str = "\xC4\xE3\xBA\xC3\xA3\xA1";
   $coding = mb_detect_encoding($str);
   print("5. ".$coding." for (\x".bin2hex($str).")\n");

   print("\nString length:\n");
   $str = "Hello!";
   $length = mb_strlen($str, "ASCII");
   print("1. ".$length." for (\x".bin2hex($str).")\n");

   $str = "\x00H\x00e\x00l\x00l\x00o\x00!";
   $length = mb_strlen($str, "UTF-16");
   print("2. ".$length." for (\x".bin2hex($str).")\n");

   $str = "\xC2\xA1Hola!";
   $length = mb_strlen($str, "UTF-8");
   print("3. ".$length." for (\x".bin2hex($str).")\n");

   $str = "\xE4\xBD\xA0\xE5\xA5\xBD!";
   $length = mb_strlen($str, "UTF-8");
   print("4. ".$length." for (\x".bin2hex($str).")\n");

   $str = "\xC4\xE3\xBA\xC3\xA3\xA1";
   $length = mb_strlen($str, "GB2312");
   print("5. ".$length." for (\x".bin2hex($str).")\n");

   print("\nString conversion - ASCII <--> UTF-16:\n");
   $str = "Hello!";
   print("   String in ASCII = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "UTF-16", "ASCII");
   print("   Converted to UTF-16 = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "ASCII", "UTF-16");
   print("   Converted to ASCII = (\x".bin2hex($str).")\n");

   print("\nString conversion - UTF-8 <--> UTF-16:\n");
   $str = "\xC2\xA1Hola!";
   print("   String in UTF-8 = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "UTF-16", "UTF-8");
   print("   Converted to UTF-16 = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "UTF-8", "UTF-16");
   print("   Converted to UTF-8 = (\x".bin2hex($str).")\n");

   print("\nString conversion - UTF-8 <--> GB2312:\n");
   $str = "\xE4\xBD\xA0\xE5\xA5\xBD!";
   print("   String in UTF-8 = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "GB2312", "UTF-8");
   print("   Converted to GB2312 = (\x".bin2hex($str).")\n");
   $str = mb_convert_encoding($str, "UTF-8", "GB2312");
   print("   Converted to UTF-8 = (\x".bin2hex($str).")\n");

   print("\nString conversion - GB2312 <--> UTF-16:\n");

   print("   Converted to GB2312 = (\x".bin2hex($str).")\n");
?>
