FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
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 PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.

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.
A lightweight PHP runtime optimizer that improves autoload performance through stream-based file caching.
Requirements
PHP >= 8.2
ext-openssl
Installation
What it does
sysgen/streamcore reduces file I/O overhead during class autoloading by intercepting the PHP stream layer and serving frequently accessed files from an in-memory buffer. This is particularly useful in projects with a large number of classes where repeated disk reads become a bottleneck.
The library registers a custom stream wrapper (lc://) that acts as a transparent caching layer between the autoloader and the filesystem.
Usage
The library boots automatically when installed via Composer. No configuration is required.
If you need to boot it manually (e.g. in a standalone script without Composer):
How it works
On boot, the library registers a prepend autoloader and a custom stream protocol (lc://).
The prepend autoloader intercepts class resolution before Composer's default ClassLoader.
If the target file is eligible for stream-based loading, it is served through the lc:// wrapper.
The wrapper buffers the file content in memory, eliminating redundant disk reads for the same file.
