function for cutting up last name

[karatekid36]

Howdy everyone,

 

    I am pulling the last name from a table and I want the name to display as First L. not First Last.  I am not sure how to do this in a function.  All I need is the first letter of the last name followed by a period.  Can anyone explain this to me?  Thank you.

<?php
function nameShort($name){
list($fN,$lN) = expolde(" ",$name);
return $fN.' '.substr($lN,0,1).'.';
}

echo nameShort($row['fname'].' '.$row['lname']);
?>
