Mysql Done Right is a PHP 5.0+ class that provides a safe, clean, object-oriented, and efficient way to do database development. All queries except those with multiple row results return exactly what you need in one line of code. This is all done while still maintaining use of prepared queries and bound parameters to eliminate the risk of SQL injection attacks and operate more efficiently. No extra coding is needed on your part to reuse prepared queries. You simply write the same query again, and if you have used that one before, the prepared handle is reused. The newly bound parameters are used against the existing prepared handle, and the results are recomputed. The results themselves are not cached. Database connectivity is implemented using MySQLi.
AS2Secure is a PHP library that allows you to send and receive AS2 (Applicability Statement 2) messages from partners. The project is split into two parts: a client to send one or more documents to a partner and a server to receive one or more documents from a partner. Its main features are asyncronous and syncronous MDN, partner setup, digital signatures, message encryption, secure transport (using OpenSSL), support for SSL client authentication, and multiple attachments (AS2 1.2).
Zebra_cURL is a high performance PHP library acting as a wrapper to PHP's libcurl library, which not only allows the running of multiple requests at once asynchronously in parallel, but as soon as one thread finishes, it can be processed right away without having to wait for the other threads in the queue to finish, 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) and POST requests, and basic downloads as well as downloads from FTP servers, HTTP Authentication, and requests 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.
