PHP mb_ucfirst Make a String’s First Character Uppercase-Multibyte (UTF-8) Function - Comment Page: 1

1. Nice function. Too bad none of your example strings contains multibyte characters, so it doesn’t really prove that your function would work with all these accents, rings, umlauts, etc.

   • Hi programmer,

     I added example with multibyte characters and of course you could try it with your own multibyte characters.

2. Thanks for sharing! Just in case somebody else stumbles on this page searching for something slightly different like me: mb_convert_case() has a flag MB_CASE_TITLE which is a faster way to make only the first character of every word upper case, then trying to split the string and then use the above mb_ucfirst() function on every segment.

   This would result in the string “YeT MORE teSTing” becoming “Yet More Testing” instead of “Yet more testing”.

3. Hi! just stumbled upon this in a time of need via google, thanks for that! :)

   however, when adjusting it to fit our coding style, i did notice it could be rewritten to be somewhat more simple, so i did some refactoring and come up with this iteration.
   thought i’d share, hope you’ll like it :)

   
if (!function_exists('mb_ucfirst'))
{
function mb_ucfirst ($str, $encoding = "UTF-8", $lower_str_end = false)
{
$first_letter = mb_strtoupper (mb_substr ($str, 0, 1, $encoding), $encoding);
$str_end = mb_substr ($str, 1, mb_strlen ($str, $encoding), $encoding);

   return $first_letter.($lower_str_end ? mb_strtolower ($str_end) : $str_end);
}
}

6. this astuce is very good for me. I’ve simply changed : function mb_ucfirst($str, $encoding = “iso-8859-1”, $lower_str_end = true)

   Big thanks :)

11. there’s no need to use mb_strlen(), the default length for mb_substr() is null, and null means “until the end of the string”, you can replace all instances of `mb_strlen($str, $encoding)` with a simple `null`

    • Thanks Hans, I have to test it, but your logic sounds right!
