How uppercase words with space and "-" between

Question

I would like to change a string with

hello teSt woRld hEllo-woRld

to

Hello Test World Hello-World

I did something, that observes only spaces between the words. But I need it for spaces and "-" between. Can someone tell me how to achieve it ?

$words = explode(" ", $string);
foreach ( $words as $key=>$value ) {
  $new .= mb_strtoupper( mb_substr( mb_strtolower( $value) , 0, 1, 'UTF-8'), 'UTF-8' ) . 
          mb_substr(mb_strtolower( $value ), 1, null, 'UTF-8') . ' ';
}

Answer 1

you should try something like this :

$string = "hello teSt woRld hEllo-woRld";
echo ucwords(strtolower($string), " -");

The second parameter of the ucwords function is the word delimiter. In this case, words are separated with either a space or a hyphen.

The result will be :

Hello Test World Hello-World

If you are concerned about keeping the UTF-8 format, you should consider using the mb_convert_case function like the example below :

$str = "mary had a Little lamb and she loved it so";
$str = mb_convert_case($str, MB_CASE_TITLE, "UTF-8");
echo $str; // Display: Mary Had A Little Lamb And She Loved It So
