For my case following did the work to capitalize UTF-8 encoded string.
function capitalize($str, $encoding = 'UTF-8') {
return mb_strtoupper(mb_substr($str, 0, 1, $encoding), $encoding) . mb_strtolower(mb_substr($str, 1, mb_strlen($str), $encoding), $encoding);
}
mb_convert_case
(PHP 4 >= 4.3.0, PHP 5)
mb_convert_case — Perform case folding on a string
Descripción
Performs case folding on a string, converted in the way specified by mode .
Lista de parámetros
- str
-
The string being converted.
- mode
-
The mode of the conversion. It can be one of MB_CASE_UPPER, MB_CASE_LOWER, or MB_CASE_TITLE.
- encoding
-
The encoding parameter is the character encoding. If it is omitted, the internal character encoding value will be used.
Valores retornados
A case folded version of string converted in the way specified by mode .
Unicode
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/.
Ejemplos
Example #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");
echo $str; // Prints MARY HAD A LITTLE LAMB AND SHE LOVED IT SO
$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
echo $str; // Prints Mary Had A Little Lamb And She Loved It So
?>

If you want to capitalize the first letter of a multibyte string, you can use this function.
<?php
function capitalize($str, $encoding = null) {
$str = mb_strtoupper($str{0}, $encoding) . mb_substr($str, 1, null, $encoding);
return $str;
}
?>

This function is a bit more flexible than using mb_convert_case with MB_CASE_TITLE, because it lets you add words whose case you don't want modified.
function title_case($string, $exceptions = array('to', 'a', 'the', 'of', 'I', 'II', 'III', 'IV', 'V', 'VI', 'VII', 'VIII', 'IX', 'X')) {
$words = split(" ", $string);
$newwords = array();
foreach ($words as $word)
{
if (!array_key_exists($word, $exceptions)) {
$word = strtolower($word);
$word = ucfirst($word);
}
array_push($newwords, $word);
}
return ucfirst(join(" ", $newwords));
}

This function will capitalize the first letter ( the same as using mb_convert_case with MB_CASE_TITLE flag, but when using a sentence, it'll only capitalize the first word )
<?php
function capitalize(&$input) {
$input = strtoupper( substr( $input , 0 , 1 ) ).strtolower( substr( $input , 1 ) );
return $input;
}
?>
Very short, uses substr, strtoupper, and strtoupper only

For CZECH characters:
<?php
$text = mb_convert_case($text, MB_CASE_LOWER, "Windows-1251");
?>
The right encoding Windows-1250 is not valid (see the list mb_list_encodings), but Windows-1251 will do the same 100%. The function strtolower() ignores czech characters with diacritics.
