How to uppercase first letter after a hyphen, ie Adam Smith-Jones

Question

I\'m looking for a way to uppercase the first letter/s of a string, including where the names are joined by a hyphen, such as adam smith-jones needs to be Adam Smith-Jones.

Answer 1

Is this ok ?

    function to_upper($name)
    {
        $name=ucwords($name);
        $arr=explode('-', $name);
        $name=array();
        foreach($arr as $v)
        {
            $name[]=ucfirst($v);
        }
        $name=implode('-', $name);
        return $name;
    }
    echo to_upper("adam smith-jones");
