How can PHP handle memory usage and execution time constraints when implementing a chat feature?

When implementing a chat feature in PHP, it's important to handle memory usage and execution time constraints to ensure the application runs smoothly. One way to achieve this is by setting appropriate memory limits and timeouts in PHP configuration or within the script itself. Additionally, using efficient data structures and algorithms can help optimize memory usage and execution time. 

// Set memory limit and max execution time
ini_set('memory_limit', '256M');
ini_set('max_execution_time', 30);
