Are there best practices for separating PHP scripts into view and control files for form handling?

When separating PHP scripts into view and control files for form handling, it is best practice to keep the form HTML in the view file and the form processing logic in the control file. This separation helps keep the code organized and maintainable. The view file should display the form and submit data to the control file, which processes the form data and performs any necessary actions. 

// view file (form_view.php)
<form action="form_control.php" method="post">
    <input type="text" name="username" placeholder="Username">
    <input type="password" name="password" placeholder="Password">
    <button type="submit">Submit</button>
</form>

// control file (form_control.php)
<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $username = $_POST["username"];
    $password = $_POST["password"];
    
    // form processing logic here
}
?>
