Description
string
mb_convert_case ( string str, int mode [, string encoding])
mb_convert_case() returns case folded version of
string converted in the way specified by
mode_
mode can be one of MB_CASE_UPPER, MB_CASE_LOWER
or MB_CASE_TITLE_
encoding specifies the encoding of
str; if omitted, the internal character encoding
value will be used_
The return value is str with the appropriate case folding applied_
By contrast to the standard case folding functions such as
strtolower() and strtoupper(),
case folding is performed on the basis of 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 (Ä)_
For more information about the Unicode properties, please see http://www_unicode_org/unicode/reports/tr21/_
Ejemplo 1_ mb_convert_case() example <?php
$str = "mary had a Little lamb and she loved it so";
$str = mb_convert_case($str, MB_CASE_UPPER, "UTF_8");
print $str; # Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
$str = mb_convert_case($str, MB_CASE_TITLE, "UTF_8");
print $str; # Prints Mary Had A Little Lamb And She Loved It So
?> |
