php - Most efficient way to get last initial? -

-

i'm working on custom forum. use email , password log in, , forum display first name , last initial. database stores first name , full last name.

what easiest way make abbreviate last name initial?

it uses display full name:

$name = $row['user_firstname'] . " " . $row['user_lastname'];

thanks!

 $name = $row['user_firstname'] . " " . $row['user_lastname'][0];

just add [0] end first character.
