Progressive JSON Streaming for PHP APIs
=======================================

[](#progressive-json-streaming-for-php-apis)

**TL;DR:** Progressive JSON Streaming sends data incrementally to show users page structure instantly while slow API calls complete in the background.

> **Stream JSON responses progressively to improve user experience.** Send page structure instantly, then fill in slow data as it becomes available. Perfect for dashboards, homepages, and APIs mixing fast cached data with slow database queries.

Perfect for dashboards, homepages, and any API where some data loads fast (cache) and some loads slow (database/external APIs).

The Problem
-----------

[](#the-problem)

```
// Traditional API: User waits 2000ms to see anything
{
  "user": "...",          // Ready in 50ms
  "posts": "...",         // Ready in 200ms
  "analytics": "..."      // Takes 2000ms ← Everything waits for this
}
```

The Solution
