Build a responsive and user-friendly local marketplace platform in PHP that allows buyers to search for goods and services from nearby sellers with ease. The platform should include an intuitive interface for sellers to create and manage their own listings, including product descriptions, pricing, and images. It should also support secure payment transactions and provide a robust messaging system for buyers and sellers to communicate. Additionally, the platform should feature powerful search capabilities, allowing users to quickly find what they are looking for by keyword, category, and location. Finally, the platform must be scalable and able to handle a high volume of traffic, with a focus on performance and reliability.
