How can error handling and feedback messages be effectively implemented in PHP registration/login scripts to provide a better user experience?

Issue: Error handling and feedback messages are important in PHP registration/login scripts to provide users with clear information about any issues they encounter during the process. Solution: Implementing error handling and feedback messages in PHP registration/login scripts can be achieved by using conditional statements to check for errors and displaying corresponding messages to the user. 

```php
// Check for errors during registration/login process
if ($error) {
    // Display error message to the user
    echo "<p>Error: $error</p>";
}
```

In this code snippet, the variable `$error` is used to store any error messages that occur during the registration/login process. If an error is detected, the script will display the error message to the user.
