How does custom exceptions behave in multithreaded code?

In multithreaded code, custom exceptions behave similarly to regular exceptions, but with additional considerations due to the concurrent nature of thread execution. When a custom exception is thrown in one thread, it won't affect the other threads unless there is a shared resource or state causing a conflict. Proper handling of custom exceptions across multiple threads is crucial to ensure that threads can recover from errors independently while maintaining overall application stability.

Example of Custom Exception in Multithreaded Code


        <?php
        class CustomException extends Exception {}

        function riskyFunction() {
            if (rand(1, 10) > 5) {
                throw new CustomException("A custom exception occurred!");
            }
            return "Function executed successfully!";
        }

        $thread1 = new Thread(function() {
            try {
                echo riskyFunction();
            } catch (CustomException $e) {
                echo "Thread 1: " . $e->getMessage();
            }
        });
        
        $thread2 = new Thread(function() {
            try {
                echo riskyFunction();
            } catch (CustomException $e) {
                echo "Thread 2: " . $e->getMessage();
            }
        });

        $thread1->start();
        $thread2->start();

        $thread1->join();
        $thread2->join();
        ?>
