How does objects behave in multithreaded code?

In multithreaded code, objects can exhibit unpredictable behavior due to concurrent access by multiple threads. Shared objects, when modified by different threads without proper synchronization, can lead to inconsistent states, race conditions, and data corruption. It is essential to implement proper synchronization mechanisms (such as locks, semaphores, or synchronized methods) to ensure that only one thread can access a mutable object at a time. This helps in maintaining the integrity of the object's state.

Example of Object Behavior in Multithreaded Environment


        <?php
        class Counter {
            private $count = 0;

            public function increment() {
                $this->count++;
            }

            public function getCount() {
                return $this->count;
            }
        }

        $counter = new Counter();

        function runInThread($counter) {
            for ($i = 0; $i < 1000; $i++) {
                $counter->increment();
            }
        }

        // Create multiple threads
        $threads = [];
        for ($i = 0; $i < 10; $i++) {
            $threads[$i] = new Thread(function() use ($counter) {
                runInThread($counter);
            });
            $threads[$i]->start();
        }

        // Wait for all threads to finish
        foreach ($threads as $thread) {
            $thread->join();
        }

        echo "Final count: " . $counter->getCount();
        ?>
