How can PHP developers prevent form fields from being pre-filled after a redirect back to a form?

When redirecting back to a form after submission, PHP developers can prevent form fields from being pre-filled by clearing the form input values. This can be achieved by setting the value attribute of each input field to an empty string or null. 

// Clear form input values to prevent pre-filling after redirect
<input type="text" name="username" value="">
<input type="password" name="password" value="">
<input type="email" name="email" value="">
