How can the use of * symbols for password input be implemented in a PHP login function?

To implement the use of * symbols for password input in a PHP login function, you can use the str_repeat() function to generate a string of * symbols equal to the length of the password input. This will help mask the actual characters of the password as the user types it in. 

$password = $_POST['password'];
$masked_password = str_repeat('*', strlen($password));

echo "Password: <input type='password' name='password' value='$masked_password'>";
