Reliable job processing
Web requests are designed to return a response. Some business jobs are designed to keep working for minutes.
When a job imports thousands of rows, sends a large batch of messages, generates many documents, or synchronizes external data, trying to do everything inside one request can create timeouts and a poor user experience. PHPRunner can provide the page, events, and progress interface around a restartable job design.
Good for short, predictable work that completes comfortably within normal request limits.
Split the work into smaller chunks and update progress between batches.
Best when the work should continue independently of the user's browser session.
Quick answer: Keep short work inside the request; split medium-size work into restartable batches; move large or independent jobs to scheduled or background processing when possible. Give users progress and preserve job state so failures can be retried safely.
Increasing a server timeout may hide the problem without making the job more reliable.
A request can be interrupted by a proxy, web server, application timeout, browser disconnect, network failure, or deployment. Long jobs also leave the user uncertain about whether anything is still happening.
The safer design reduces the amount of work that must succeed in one request.
Process a controlled number of records, save progress, then continue.
Identify the records or work to process and store enough state to know the total and current position.
Handle a small number of records and record successes and errors.
Update the user with completed, remaining, and error counts.
Start the next batch, or resume from the last known state after a failure.
A retry should not accidentally repeat completed business effects.
If an email was already sent or an invoice already generated, restarting the job should know that. Store per-item status or use unique identifiers so the system can distinguish completed work from work that still needs processing.
This becomes even more important for background jobs because the user may not be watching when a retry occurs.
The goal is to keep the architecture understandable while reducing repetitive application work.
PHPRunner can implement AJAX-driven batch workflows, scheduled processing, progress displays, and custom job state around the application's database.
| Need | PHPRunner approach |
|---|---|
| Batch actions | Process a limited number of records per request and continue from client-side or server-side logic. |
| Progress UI | Display counts, status, and errors while the operation continues. |
| Scheduled work | Run recurring or independent processing through the scheduling approach supported by your deployment environment. |
| Job records | Use normal database tables to store queue and status information so work can be resumed and audited. |
Long-running work becomes reliable when it is restartable.
Instead of asking one request to survive for ten minutes, design the job so each step is small, observable, and repeatable.
Users get better feedback, failures affect less work, and the application becomes easier to operate.
