Description
string
mb_strtolower ( string str [, string encoding] )
mb_strtolower() returns str
with all alphabetic characters converted to lowercase.
encoding specifies the encoding of
str; if omitted, the internal character encoding
value will be used.
For more information about the Unicode properties, please see http://www.unicode.org/unicode/reports/tr21/.
By contrast to strtolower(), '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 (Д).
Пример 1. mb_strtolower() example
<?php
$str = "Mary Had A Little Lamb and She LOVED It So";

?>
