    The sscanf() function is to some extent the opposite of sprintf(), in that it extracts values from a string based on a formatting string.

    What is the output of the following PHP script?

    
    <?php
        $str 'I am 30';
    
        $vals sscanf($str'%s %d');
    
        echo trim($vals[0] . ' ' $vals[1]);
    ?>
