Keeping first letter uppercase and rest lowercase with International letter support

Question

I am using this code to keep first letter uppercase and rest lowercase but it doesn't support international latin letters. What should i add to make it support?

str_replace('\' ', '\'', ucwords(str_replace('\'', '\' ', strtolower($name))))

EDIT: ucfirst doesn't do it because i need each word's first letter uppercase

Example: HELLO BABY HOW ARE YOU

I need it like: Hello Baby How Are You

Answer 1

This works for international chars also:

mb_convert_case($str, MB_CASE_TITLE, "UTF-8");

Answer 2

You can use ucwords with strtolower

$string ="HELLO BABY HOW ARE YOU";
echo ucwords(strtolower($string));

Outputs :

Hello Baby How Are You.

Answer 3

You can first use strtolower to make the string lowercase before passing to ucwords.

ucwords does work with international characters, providing the correct locale is set.

See documentation on setlocale: http://php.net/manual/en/function.setlocale.php

You will need to set LC_CTYPE which is used for character classification and conversion.

Example for German characters:

setlocale(LC_CTYPE, 'de');
$a = ucwords(strtolower($b));

Here's the code:

function capitalizeFirstLetter($sentence){
    $result = "";
    $words = explode(" ", $sentence);
    for($i=0; $i<sizeof($words); $i++){
        $words[$i] = strtolower($words[$i]);
        $words[$i] = ucfirst($words[$i]);
        $result .= $words[$i];
        if($i != (sizeof($words) - 1)){
            $result .= " ";
        }
    }
    return $result;
}

$test = "HELLO BABY HOW ARE YOU";
echo capitalizeFirstLetter($test);

I couldn't find a way to avoid a loop.

Answer 5

Have you looked at using ucfirst? Here is the documentation.

Someone posted code for a sentence_case version ucfirst in the comments section.
