What are the steps to integrate PHP variables like Nickname, Password, and Submit into an HTML form for proper functionality?

To integrate PHP variables like Nickname, Password, and Submit into an HTML form for proper functionality, you need to use the PHP `echo` statement within the HTML form tags to display the variables. This way, when the form is submitted, the values entered by the user will be sent to the PHP script for processing. 

<form method="POST" action="process_form.php">
    <label for="nickname">Nickname:</label>
    <input type="text" name="nickname" value="<?php echo isset($_POST['nickname']) ? $_POST['nickname'] : ''; ?>"><br>
    
    <label for="password">Password:</label>
    <input type="password" name="password"><br>
    
    <input type="submit" name="submit" value="Submit">
</form>
