What are common errors or pitfalls when working with oAuth in PHP, and how can they be avoided?

Issue: One common error when working with oAuth in PHP is not properly handling token expiration. To avoid this, always check the token expiration time and refresh it before making any API calls. 

// Check token expiration time and refresh if needed
if ($token_expiration_time < time()) {
    $new_token = refresh_token($refresh_token);
    // Update token in database or session
}
```

Issue: Another pitfall is not securely storing oAuth tokens, which can lead to security vulnerabilities. To avoid this, always encrypt and securely store tokens in a database or session.

```php
// Encrypt and securely store oAuth tokens
$encrypted_token = encrypt_token($token);
// Store encrypted token in database or session
```

Issue: Handling oAuth callback URLs incorrectly can also cause errors. Make sure to properly configure callback URLs in your oAuth provider settings and handle the callback response in your PHP code.

```php
// Handle oAuth callback response
if (isset($_GET['code'])) {
    $code = $_GET['code'];
    // Exchange code for access token
    $access_token = exchange_code_for_token($code);
}
