What are some best practices for handling error-handling in PHP forum implementations?

When handling errors in PHP forum implementations, it is important to provide clear and informative error messages to users to help them understand the issue. Additionally, logging errors to a file or database can help in troubleshooting and resolving issues. Implementing try-catch blocks can help in gracefully handling exceptions and preventing the forum from crashing.

try {
    // Code that may throw an exception
} catch(Exception $e) {
    // Log the error to a file or database
    error_log($e->getMessage(), 3, "error.log");

    // Display a user-friendly error message
    echo "An error occurred. Please try again later.";
}
