Oh, right, you needed the $link to call the function. So maybe this:

PHP Code:

function si_mysqlistats() {
    $link = mysqli_connect("localhost", "dbusername", "dbpassword", "dbname");
    $status = explode('  ', mysqli_stat($link));
    mysqli_close($link);

    $s = '';
    while ( list($k, $v) = each($status) ) {
        $s .= $v . '<br />';
    }
    return $s;    
} 


And if you already have an open connection somewhere in the program, it would probably be better to change the function to take it as a parameter instead of opening another connection.
