Zebra_Session is a PHP class that acts as a wrapper for PHP’s default session handling functions. Instead of storing session data in flat files, it stores them in a MySQL database, thus providing both better security and better performance. The Zebra_Session class is also a solution for applications that are scaled across multiple Web servers (using a load balancer or a round-robin DNS) and where the user’s session data needs to be available, since storing sessions in a database makes them available to all of the servers. Zebra_Session‘s code is heavily commented and generates no warnings, errors, or notices when PHP’s error reporting level is set to E_ALL.
Zebra_Image is a compact (one file only), lightweight, object-oriented image manipulation library, written in and for PHP, that provides methods for performing several types of image manipulation operations. It doesn’t require any external libraries other than the GD2 extension (with which PHP usually comes pre-compiled). The code is heavily commented and generates no warnings/errors/notices when PHP’s error reporting level is set to E_ALL. It can rescale, flip, rotate, and crop images. It supports loading and saving images in the GIF, JPEG, and PNG formats and preserves transparency for GIF, PNG, and PNG24. It can re-size images to an exact given width and height and still maintain aspect ratio.
Zebra_Pagination is a generic pagination PHP library which automatically generates HTML navigation links (next, previous, specific pages) given the total number of records and the number of records to be displayed per page. It can generate links both in natural and in reverse order, can be easily localized, supports page propagation via GET or via URL rewriting, lets the appearance be easily customized through CSS, and is SEO-friendly (it uses rel="prev" and rel="next", and solves the problem of duplicate content on the first page without navigation and the first page having the page number in the URL). Please note that this is a *generic* pagination PHP library, meaning that it does not display any records. It is up to the developer to fetch the actual data and display it based on the information returned by this class. The advantage is that it can be used to paginate records coming from any source (arrays, database, etc). Zebra_Pagination's code is heavily commented and generates no warnings/errors/notices when PHP's error reporting level is set to E_ALL.
losetup-utils are three bash scripts that attempt to make the use of losetup a bit easier and faster. losetup can be fast, easy, and practical if you need to transport sensitive information over the Internet or in CD's, DVD's, or a pendrive. Also, if you want to store private data on your hard disk or in the cloud, an encrypted volume can be a convenient choice. The types of encryption can be any installed on the system.
