What is the recommended approach for error handling in PHP scripts, especially when dealing with database interactions?

When dealing with database interactions in PHP scripts, it is recommended to use try-catch blocks to handle any potential errors that may occur. This allows you to gracefully catch and handle exceptions that may arise during database operations, such as connection errors or query failures. By using try-catch blocks, you can prevent your script from crashing and provide informative error messages to help with troubleshooting.

try {
    // Connect to the database
    $pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');
    
    // Set PDO to throw exceptions on error
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    
    // Perform database operations
    $stmt = $pdo->prepare("SELECT * FROM users");
    $stmt->execute();
    
    // Process the results
    while ($row = $stmt->fetch()) {
        // Do something with the data
    }
} catch (PDOException $e) {
    // Handle any database errors
    echo "Database error: " . $e->getMessage();
}
