UNICODE

	For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/.

	By  contrast  to strtolower(3), 'alphabetic' is determined by the Unicode character properties. Thus the behaviour of this function is not
       affected by locale settings and it can convert any characters that have 'alphabetic' property, such as A-umlaut (A).

	      <?php
	      $str = "Mary Had A Little Lamb and She LOVED It So";
	      $str = mb_strtolower($str);
	      echo $str; // Prints mary had a little lamb and she loved it so
	      ?>
