What will be the output of the following PHP code ?

<?php
function str($Message)
    {
        $Message = ucwords($Message);
        echo lcfirst($Message);
    }
str("this is important...");
?>

1. this Is Important...
2. this is important...
3. Error
4. Nothing
5. None of these

Correct Option: A

ucwords() changes all the first letters to capitals. lcfirst() changes first letter of a string to small.
