Background Jobs and Queues (Scale PHP Like a Pro)

Some tasks are slow:

• sending email
• generating PDFs
• resizing images
• exporting CSV

If you do them during the HTTP request, your page feels slow and can time out.

Better design: Queue

  B --> C[(Queue)]
  D[Worker] --> C
  D --> E[Do heavy work]

Common queue tools

• Redis queues
• RabbitMQ
• database queue (small projects)

Frameworks like Laravel make this very smooth, but the concept is universal.

Next: Build a simple API response standard (consistent error and success shapes).
