Zebra cURL  

A high-performance solution for making HTTP requests from your PHP projects. It allows running of multiple requests concurrently, asynchronously, supports GET, POST, HEADER, PUT, PATCH, and DELETE requests, and offers support for caching, FTP downloads, HTTP authentication and proxy requests.

Zebra cURL is a high performance cURL PHP library which not only allows the running of multiple asynchronous requests at once, but also finished threads can be processed right away without having to wait for the other threads in the queue to finish.

Also, each time a request is completed another one is added to the queue, thus keeping a constant number of threads running at all times and eliminating wasted CPU cycles from busy waiting. This result is a faster and more efficient way of processing large quantities of cURL requests (like fetching thousands of RSS feeds at once), drastically reducing processing time.

This script supports GET (with caching), POST, HEADER, PUT, PATCH and DELETE requests, basic downloads as well as downloads from FTP servers, HTTP Authentication, and requests made through proxy servers.

For maximum efficiency downloads are streamed (bytes downloaded are directly written to disk) removing the unnecessary strain from the server of having to read files into memory first, and then writing them to disk.

The code is heavily commented and generates no warnings/errors/notices when PHP's error reporting level is set to E_ALL.
