PHP was the backbone for all the server-side heavy lifting - processing ticket sales, managing user accounts, and keeping the event calendar updated. MySQL handles all the data storage, from customer information to seat availability, and I spent a lot of time optimizing queries because nobody wants to wait around when they're trying to buy tickets. The JavaScript and AJAX integration was key for making the booking process feel smooth. Instead of refreshing the page every time someone selects a seat or changes their ticket quantity, everything updates in real-time. It makes the whole experience feel more modern and responsive, which is especially important when people are making purchase decisions.
