What are some common pitfalls or errors that developers may encounter when implementing a new gateway in PHP, and how can they be resolved?

One common pitfall when implementing a new gateway in PHP is not properly handling errors or exceptions that may occur during the transaction process. To resolve this, developers should implement error handling mechanisms such as try-catch blocks to catch and handle any exceptions that are thrown. 

try {
    // Code to process gateway transaction
} catch (Exception $e) {
    // Handle the exception, log the error, and notify the user
    echo "An error occurred: " . $e->getMessage();
}
