How would one add a php script like the one below in elementor?

<?php

//if the submit button is clicked, follow logic to insert record
if (isset($_POST['submit'])) {

    $insert_value = 1;

    //make a database connection
    $conn = mysqli_connect('localhost', 'myuser', 'mypassword', 'motordata');    

    //prepared statement to insert the record
    $stmt_insert_record = $conn->prepare("INSERT INTO MotorOn (command) VALUES (?)");
    $stmt_insert_record->bind_param("i", $insert_value);
    $stmt_insert_record->execute();
    $stmt_insert_record->close();
}
?>

<!-- Form that will submit to the document's address ie. the same page-->
<form method="post">
    <input type="submit" value="Shutdown" style="background-color: red;">
</form>
