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. You can look here for more information.

  • 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.
Please rate this library. Is it a good library?

Informations about the package composer-constraints-parser

Composer Constraints Parser

Composer Constraints Parser is a PHP Experts, Inc., Project that is a clean-room implementation of Packagist's composer's version constraint system.

It is meant as a zero-dependency option to faithfully interpret whether any particular version number is satisfiable by a composer verison constraint.

NOTE: 95% of this code was generated by the autonomous AI agents of Autonomo, by Autonomous Programming, LLC. See https://gist.github.com/hopeseekr/fdb0ff9bd0957ea8d226ccc2def88d99

This project contains 100% of all of the in-the-world composer version constraints of every dependency of every package in the entire packagist.org database. These can be found in [tests/constraints.json].

There are 155,623 test assertions testing all 48,209 in-the-wild composer version constraints and has 100% fidelity. It is current as of 2025-04-01.

This is possible because of the Bettergist Collector API, which archives every PHP packagist package weekly and does deep analysis of them quarterly.
