What role does error handling play in ensuring the successful insertion of arrays into a database using PHP and MySQL?

Error handling plays a crucial role in ensuring the successful insertion of arrays into a database using PHP and MySQL. It helps in identifying and resolving any issues that may occur during the insertion process, such as database connection errors, syntax errors, or data validation errors. By implementing proper error handling techniques, developers can ensure that the insertion process is smooth and error-free. 

// Connect to the database
$connection = new mysqli("localhost", "username", "password", "database");

// Check for connection errors
if ($connection->connect_error) {
    die("Connection failed: " . $connection->connect_error);
}

// Define the array to be inserted
$data = array(
    'name' => 'John Doe',
    'email' => 'john.doe@example.com',
    'age' => 30
);

// Prepare the SQL query
$sql = "INSERT INTO users (name, email, age) VALUES (?, ?, ?)";
$stmt = $connection->prepare($sql);

// Bind parameters and execute the query
$stmt->bind_param("ssi", $data['name'], $data['email'], $data['age']);
if ($stmt->execute()) {
    echo "Record inserted successfully";
} else {
    echo "Error: " . $connection->error;
}

// Close the connection
$connection->close();
