title: Laravel's Concurrency Control
body: <p>I am designing a ticket purchase system using Laravel, and I was wondering how Laravel resolves concurrency - if at all (or is it all done in database?). Can concurrent transactions occur, and how does Laravel know they are taking place? I was looking at using this plugin called <a href="https://github.com/Attendize/Attendize" rel="nofollow noreferrer">Attendize</a> and using the plugin, I want to efficiently handle concurrent transactions. Any ideas?</p>
