What is the purpose of creating custom exceptions in PHP?

Creating custom exceptions in PHP allows developers to handle specific error cases in a more organized and controlled manner. By defining custom exception classes, developers can throw and catch exceptions that are tailored to their application's needs, providing more detailed information about the error that occurred. This can help improve code readability, maintainability, and overall error handling in PHP applications. 

// Custom exception class
class CustomException extends Exception {}

// Example usage
try {
    // Code that may throw an exception
    throw new CustomException('This is a custom exception message');
} catch (CustomException $e) {
    // Handle the custom exception
    echo 'Custom Exception: ' . $e->getMessage();
}
