mb_convert_case

(PHP 4 >= 4.3.0, PHP 5)

mb_convert_caseModifie la casse d'une chaîne

Description

string mb_convert_case ( string $str , int $mode= MB_CASE_UPPER [, string $encoding= mb_internal_encoding() ] )

Effectue la modification de la casse de la chaîne spécifiée, suivant le mode spécifié.

Liste de paramètres

str

La chaîne à convertir.

mode

Le mode de conversion. Peut être un parmi : MB_CASE_UPPER, MB_CASE_LOWER, ou MB_CASE_TITLE.

encoding

Le paramètre encoding est l'encodage des caractères. S'il est omis, l'encodage de caractres interne sera utilisé.

Valeurs de retour

La chaîne dont la casse a été changée, suivant le mode fourni.

Unicode

Contrairement aux fonctions standards comme strtolower() et strtoupper(), la modification est réalisée en se basant sur le dictionnaire Unicode. Par conséquent, le comportement de cette fonction n'est pas modifié par des configurations locales, et il peut convertir n'importe quelle caractère qui a des propriétés alphabétiques, comme le a majuscule tréma (A-umlaut, Ä).

as the previouly posted version of this function doesn't handle UTF-8 characters, I simply tried to replace ucfirst to mb_convert_case, but then any previous case foldings were lost while looping through delimiters.
So I decided to do an mb_convert_case on the input string (it also deals with words is uppercase wich may also be problematic when doing case-sensitive search), and do the rest of checking after that.

As with mb_convert_case, words are capitalized, I also added lowercase convertion for the exceptions, but, for the above mentioned reason, I left ucfirst unchanged.

Now it works fine for utf-8 strings as well, except for string delimiters followed by an UTF-8 character ("Mcádám" is unchanged, while "mcdunno's" is converted to "McDunno's" and "ökrös-TÓTH éDUa" in also put in the correct form)

I use it for checking user input on names and addresses, so exceptions list contains some hungarian words too.

<?php

function titleCase($string, $delimiters = array(" ", "-", ".", "'", "O'", "Mc"), $exceptions = array("út", "u", "s", "és", "utca", "tér", "krt", "körút", "sétány", "I", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X", "XI", "XII", "XIII", "XIV", "XV", "XVI", "XVII", "XVIII", "XIX", "XX", "XXI", "XXII", "XXIII", "XXIV", "XXV", "XXVI", "XXVII", "XXVIII", "XXIX", "XXX" )) {
      
/*
        * Exceptions in lower case are words you don't want converted
        * Exceptions all in upper case are any words you don't want converted to title case
        *   but should be converted to upper case, e.g.:
        *   king henry viii or king henry Viii should be King Henry VIII
        */
       
$string = mb_convert_case($string, MB_CASE_TITLE, "UTF-8");

       foreach (
$delimiters as $dlnr => $delimiter){
              
$words = explode($delimiter, $string);
              
$newwords = array();
               foreach (
$words as $wordnr => $word){
              
                       if (
in_array(mb_strtoupper($word, "UTF-8"), $exceptions)){
                              
// check exceptions list for any words that should be in upper case
                              
$word = mb_strtoupper($word, "UTF-8");
                       }
                       elseif (
in_array(mb_strtolower($word, "UTF-8"), $exceptions)){
                              
// check exceptions list for any words that should be in upper case
                              
$word = mb_strtolower($word, "UTF-8");
                       }
                      
                       elseif (!
in_array($word, $exceptions) ){
                              
// convert to uppercase (non-utf8 only)
                            
                              
$word = ucfirst($word);
                              
                       }
                      
array_push($newwords, $word);
               }
              
$string = join($delimiter, $newwords);
       }
//foreach
      
return $string;
}

Building upon Justin's and Alex's work...

This function allows you to specify which delimiter(s) to explode on (not just the default space). Now you can correctly capitalize Irish names and hyphenated words (if you want)!

<?php
function titleCase($string, $delimiters = array(" ", "-", "O'"), $exceptions = array("to", "a", "the", "of", "by", "and", "with", "II", "III", "IV", "V", "VI", "VII", "VIII", "IX", "X")) {
      
/*
        * Exceptions in lower case are words you don't want converted
        * Exceptions all in upper case are any words you don't want converted to title case
        *   but should be converted to upper case, e.g.:
        *   king henry viii or king henry Viii should be King Henry VIII
        */
      
foreach ($delimiters as $delimiter){
              
$words = explode($delimiter, $string);
              
$newwords = array();
               foreach (
$words as $word){
                       if (
in_array(strtoupper($word), $exceptions)){
                              
// check exceptions list for any words that should be in upper case
                              
$word = strtoupper($word);
                       } elseif (!
in_array($word, $exceptions)){
                              
// convert to uppercase
                              
$word = ucfirst($word);
                       }
                      
array_push($newwords, $word);
               }
              
$string = join($delimiter, $newwords);
       }
       return
$string;
}
?>

Retouching Alex's example so it works:

function titleCase($string, $exceptions = array('to', 'a', 'the', 'of', 'by', 'and', 'with', 'UI', 'V','X')) {
   
        $words = explode(" ", $string);
        $newwords = array();
        foreach ($words as $word)
        {
            if (!in_array($word, $exceptions)) {

                $word = strtolower($word);
                $word = ucfirst($word);
            }
            array_push($newwords, $word);
        }
        return join(" ", $newwords);
    }       

It doesn't work for Irish names, etc. So keep that in mind.

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);
}

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.
