I have fname and lname in my database, and a name could be stored as JOHN DOE or john DOE or JoHN dOE, but ultimately I want to display it as John Doe
fname being Jo
seeing it is tagged PHP:
either
string ucfirst ( string $str );
to uppercase first letter of the first word
or
string ucwords ( string $str );
to uppercase the first letter of every word
you might want to use those in combination with
string strtolower ( string $str );
to normalize all names to lower case first.
