How can error handling be improved in PHP to provide informative messages to users without causing confusion?

Error handling in PHP can be improved by using custom error messages that provide specific information to users without revealing sensitive details. One way to achieve this is by using try-catch blocks to catch exceptions and then display user-friendly error messages. Additionally, utilizing error logging functions like error_log() can help developers track and troubleshoot errors without exposing them to users.

try {
    // Code that may throw an exception
    throw new Exception("Something went wrong. Please try again later.");
} catch (Exception $e) {
    // Display a user-friendly error message
    echo "An error occurred: " . $e->getMessage();
    // Log the error for debugging purposes
    error_log("Error: " . $e->getMessage());
}
