About

The MemoryCache class provides a mechanism for caching data in shared memory using PHP's shmop functions. This is useful for performance optimization by reducing the need to repeatedly fetch data from slower storage mediums.

Requirements

This requires shmop to be active with your PHP settings.

Available methods

openMemory

Opens a shared memory block and returns the memory identifier.

writeJsonInMemory

Writes JSON-encoded data to the shared memory.

readJsonInMemory

Reads data from the shared memory and decodes it from JSON.

Usage

$cache = new MemoryCache();
$data = ['key' => 'value'];
$cache->writeJsonInMemory($data);
$retrievedData = $cache->readJsonInMemory();

Testing

Unit tests for the MemoryCache class are available in the tests/MemoryCacheTest.php file.
