What are the limitations in preventing browsers from saving passwords for PHP websites?

The limitations in preventing browsers from saving passwords for PHP websites lie in the fact that browsers have their own mechanisms for saving and autofilling passwords, which can override any attempts made by the website to prevent this behavior. One way to address this issue is to use the `autocomplete="off"` attribute in the HTML form fields where passwords are entered, although this is not a foolproof solution. 

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