How can new users be encouraged to follow forum rules and guidelines in PHP discussions?

New users can be encouraged to follow forum rules and guidelines in PHP discussions by prominently displaying the rules when they first join the forum, providing clear explanations of the consequences of not following the rules, and actively moderating the discussions to enforce the rules.

// Display forum rules when new user joins
echo "Welcome to our PHP discussion forum! Please make sure to read and follow our forum rules.";

// Provide consequences of not following rules
echo "Failure to adhere to our rules may result in warnings, suspensions, or bans.";

// Actively moderate discussions to enforce rules
// Implement moderation features here
