Just like any other extension. If it's WampServer you're using, click on it's icon in tray, go to PHP > PHP Extensions  and make sure there's a tick next to php_mysqli. If it's there already (by default it should) then there's something else wrong with what you're doing.

here bro see

 

<?php
//check for required fields from the form
if ((!$_POST["topic_owner"]) || (!$_POST["topic_title"]) ||
(!$_POST["post_text"])) {
     header("Location: addtopic.html");
     exit;
}

//connect to server
$mysqli = mysqli_connect("localhost", "root", "demo", "forums");

//create and issue the first query
$add_topic = "INSERT INTO forum_topics (topic_title, topic_create_
              time, topic_owner) VALUES ('".$_POST["topic_title"]."',now(),
               '".$_POST["topic_owner"]."')";
$add_topic_res = mysqli_query($mysqli, $add_topic_sql)
                  or die(mysqli_error($mysqli));

//get the id of the last query
$topic_id = mysqli_insert_id($mysqli);

//create and issue the second query
$add_post_sql = "INSERT INTO forum_posts (topic_id,post_text,
                  post_create_time, post_owner) VALUES ('".$topic_id."',
                 '".$_POST["post_text"]."', now(),
                 '".$_POST["topic_owner"]."')";
$add_post_res = mysqli_query($mysqli, $add_post_sql)
                 or die(mysqli_error($mysqli));

  //close connection to mysqli
mysqli_close($mysqli);

//create nice message for user
$display_block = "<P>The <strong>".$_POST["topic_title"]."</strong>
topic has been created.</p>";
?>
<html>
<head>
<title>New Topic Added</title>
</head>
<body>
<h1>New Topic Added</h1>
<?php echo $display_block; ?>
</body>
</html>

Comment these lines at the start out

if ((!$_POST["topic_owner"]) || (!$_POST["topic_title"]) || (!$_POST["post_text"]))
{
header("Location: addtopic.html");
exit;
}

 

And do as Mchl stated with the echo. If this works, but doesn't work when the above line is uncommented.. then theres your problem.

If the echo does get displayed, then it might be that Mysqli is having issues somewhere...

 

(Sorry for reviving old post, it hasn't been noted if the problem has been fixed)
