FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

guzzle-apcu-fs-cache
A zero config cache storage for guzzle-cache-middleware that tries to cache on Apcu and fallbacks to filesystem.

Using composer:
Usage
This is an example of how you can use this storage engine with Guzzle and GuzzleCacheMiddleware:
Use with Launch Darkly PHP SDK
If you want to use this cache storage with the Launch Darkly PHP SDK, here's how you can do it:
Configuration
The storage layer can be configured at construction time.
These are the following parameters accepted by the constructor:
- (string)
$dir: The directory where the cache should be saved if using the filesystem (Default: the temp directory). - (string)
$namespace: A namespace for the cache storage, useful when using multiple instances and cache should not be mixed between them. It will create a subfolder on the filesystme and a prefix on APC. (Default:'default'). - (integer)
$ttlThe duration of a cache entry in seconds (Default:60). - (callable)
$onHitAn optional function that gets called when there's a cache hit. - (callable)
$onMissAn optional function that gets called when there's a cache miss.
If you want to inspect whether your current instance is using APC or the filesystem you can use the following public properties:
$storage->usingApcu(returnstrueorfalse)$storage->usingFilesystem(returnstrueorfalse)
Rationale and Notes
This was originally created to cache requests made by the Launch Darkly client in a more controlled and configurable way.
Note: this middleware will always respect the TTL you provide and will ignore any HTTP cache header returned as response. This is by design. Use this middleware only if you want to enforce cache or for micro-caching scenarios (e.g. very expensive and frequent API calls).
