How can the HTML structure affect the indexing of form data in PHP?

The HTML structure can affect the indexing of form data in PHP by determining the format in which the data is sent to the server. To ensure proper indexing of form data in PHP, the form fields should have unique names and be structured correctly within the HTML form. This allows PHP to access the form data using the $_POST or $_GET superglobals based on the form submission method. 

<form method="post" action="process_form.php">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Submit</button>
</form>
