PHP is a single-threaded language, but Laravel can handle queue jobs asynchronously using multiple workers. Each worker is a separate long-running PHP process that listens for and processes jobs from a queue backend like Redis or a database. Tools like Supervisor manage these workers in production, ensuring they run continuously. This design allows Laravel to handle tasks in parallel, improving performance and user experience.
