How can one ensure that user input in PHP form fields is treated as plain text and not interpreted as HTML code?

To ensure that user input in PHP form fields is treated as plain text and not interpreted as HTML code, you can use the `htmlspecialchars()` function to escape any HTML characters in the input. This function will convert characters like `<`, `>`, `&`, and `"` to their HTML entity equivalents, preventing them from being interpreted as HTML code when displayed on a webpage. 

// Get user input from form field
$userInput = $_POST[&#039;user_input&#039;];

// Escape HTML characters in user input
$userInput = htmlspecialchars($userInput);

// Now $userInput can be safely displayed as plain text without being interpreted as HTML code
