PHP Luminova: Runtime Shared Memory

The Luminova boot module does more than just autoloading and application warmup. It includes a Shared Memory feature, a lightweight in-memory storage for application key/value data. It allows you save and read values during a single request. It works like a small “notepad” in memory that your application can share while it is running.

This is not real saved storage. Once the request ends, everything is gone.Think of it like temporary notes on a whiteboard that gets wiped clean after each request.

What this storage can do

• Save a value under a key
• Read it back later
• Check if a key exists
• Remove a key
• Clear all keys
• Count how many items are stored

This storage is:

Useful when you want to share values between different parts of your application without using session or passing them around manually.

• In-memory only
• Lost after each request
• Not shared between workers
• Not saved to disk

Usages

use Luminova\Boot;

// Store a value
Boot::set('theme', 'dark');

// Get a value
$theme = Boot::get('theme') ?? 'light';

// Check if it exists
if (Boot::has('theme')) {
    // ...
}

// Remove one value
Boot::remove('theme');

// Clear everything
Boot::clear();

// Count how many keys are stored
$count = Boot::count();
