What is the significance of considering the context switch to HTML when working with PHP code in forms?

When working with PHP code in forms, it is important to consider the context switch to HTML in order to properly display the form elements and handle user input. This involves using HTML tags within the PHP code to structure the form elements and ensure they are displayed correctly on the webpage. By incorporating HTML within the PHP code, you can create a seamless user experience and effectively process form submissions.

<form action="process_form.php" method="post">
  <label for="username">Username:</label>
  <input type="text" id="username" name="username">
  
  <label for="password">Password:</label>
  <input type="password" id="password" name="password">
  
  <input type="submit" value="Submit">
</form>
