how to convert pdo to mysqli

I'm use  this tutorial, but my issue is that everything is written for PDO,

but the my website is MySQLi.

I've been trying to just search for conversions on www.php.net (for example; $statement = $db->prepare($query); = $statement = $db->mysqli_prepare($query) (source))

This is my code that doesn't work:


    $query = "
        SELECT shape FROM inventory

    $statement = $db->mysqli_prepare($query)
    $result = $statement->mysqli_fetch()

    foreach($result as $row) {


        <!-- HTML code here -->

<?php } ?>

It's supposed to query the shape column from the database but I keep getting this error Fatal error:

Uncaught Error: Call to a member function stmt_init() on null in /homepages/7/d410968336/htdocs/Inventory/vendors/php/Filters/Filters.php:68 Stack trace: #0 {main} thrown in /homepages/7/d410968336/htdocs/Inventory/vendors/php/Filters/Filters.php on line 68 (in this case line 7 $statement = $db->mysqli_prepare($query))

Answer :

Good , first in a simple select query you really don't need the prepared statement.

but if you do I think this would help you.

$query = "SELECT shape FROM inventory"; $statement = mysqli_prepare($db, $query); mysqli_stmt_execute($statement); while(mysqli_stmt_fetch($statement)){ .... }
