You can execute a callback in a synchronized mode i.e. only a\nsingle instance of the callback is executed at the same time:\n\n```php\n$synchronizer = new \\Yiisoft\\Mutex\\Synchronizer($mutexFactory);\n\n$newCount = $synchronizer-\u003eexecute('critical', function () {\n    return $counter-\u003eincrease();\n}, 10);\n```\n\nAnother way is to manually open and close mutex:\n\n```php\n$simpleMutex = \\Yiisoft\\Mutex\\SimpleMutex($mutexFactory);\n\nif (!$simpleMutex-\u003eacquire('critical', 10)) {\n    throw new \\Yiisoft\\Mutex\\Exception\\MutexLockedException('Unable to acquire the \"critical\" mutex.');\n}\n\n$newCount = $counter-\u003eincrease();\n$simpleMutex-\u003erelease('critical');\n```\n\nIt could be done on lower level:\n\n```php\n$mutex = $mutexFactory-\u003ecreateAndAcquire('critical', 10);\n$newCount = $counter-\u003eincrease();\n$mutex-\u003erelease();\n```\n\nAnd if you want even more control, you can acquire mutex manually:\n\n```php\n$mutex = $mutexFactory-\u003ecreate('critical');\n\nif (!$mutex-\u003eacquire(10)) {\n    throw new \\Yiisoft\\Mutex\\Exception\\MutexLockedException('Unable to acquire the \"critical\" mutex.');\n}\n\n$newCount = $counter-\u003eincrease();\n$mutex-\u003erelease();\n```\n\nThe `PgsqlMutex` supports the \"wait for a lock for a certain time\" functionality. Using the `withRetryDelay()`\nmethod, you can override the number of milliseconds between each try until specified timeout times out:\n\n```php\n$mutex = $mutex-\u003ewithRetryDelay(100);\n```\n\nBy default, it is 50 milliseconds - it means that we may try to acquire lock up to 20 times per second.\n\n## Documentation\n\n- [Internals](docs/internals.md)\n\nIf you need help or have a question, the [Yii Forum](https://forum.yiiframework.com/c/yii-3-0/63) is a good place for that.\nYou may also check out other [Yii Community Resources](https://www.yiiframework.com/community).\n\n## License\n\nThe Yii Mutex Library - PostgreSQL PDO Driver is free software.
