How can developers ensure the security of API keys and sensitive data in PHP applications when handling exceptions?

Developers can ensure the security of API keys and sensitive data in PHP applications when handling exceptions by using environment variables to store these sensitive information and ensuring they are not exposed in error messages or logs. 

// Set API key as environment variable
$apiKey = getenv('API_KEY');

// Use try-catch block to handle exceptions
try {
    // Code that may throw exceptions
} catch (Exception $e) {
    // Log or handle the exception without exposing sensitive data
}
