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. 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 carl

🧊 Carl

Immutable HTTP client for PHP built on cURL. Pure OOP, no null, no static.
Inspired by Elegant Objects and cactoos.

Features

Final, immutable classes with single responsibility
No null values anywhere
No static methods or state
Lazy evaluation of HTTP requests
Built-in fake clients and responses for testing
No external dependencies except PHP and cURL

Simple Request Example

Parallel Requests with onSuccess and onFailure

🧪 Testing with Fakes

Carl provides fake classes for isolated unit testing without real HTTP calls. You can replace the real client with FakeClient to drive predefined outcomes.

Examples of fake outcomes:

AlwaysSuccessful — always returns success (HTTP 200)
AlwaysFails — always returns a failure with a given error message
Cycle — cycles through a list of outcomes in order
FakeStatus — returns an outcome with HTTP status code derived from the URI path

Example usage:

💤 Lazy Evaluation

Carl objects are lightweight and perform no heavy work in constructors. Network I/O occurs only when you call outcome() or outcomes(). Response parsing/consumption (e.g., body()) is deferred until you access it. This keeps composition predictable and fast.
