Ignoring Error Handling
- Mistake: Overlooking error handling can result in unexpected behaviors and security risks.
// Mistaken code
$result = $pdo->query("SELECT * FROM users");
- Correction: Implement try-catch blocks to gracefully handle exceptions, enhancing application robustness.
Syntax:
try {
// Code that may throw an exception
} catch (Exception $e) {
// Handle the exception
}
