Zebra_Form is a PHP class that simplifies the process of creating and validating HTML forms. Its object-oriented structure promotes rapid HTML forms development and encourages developers to write clean and easily maintainable code. It frees the developers from the repetitive task of writing the code for validating forms by offering powerful built-in client-side and server-side validation. Zebra_Form has an integrated cross-site scripting prevention mechanism that automatically strips out potentially malicious code from the submitted data. It also prevents automated SPAM posts, out of the box and without relying on CAPTCHA by using honey pots. Output can be generated either automatically or manually through templates (basic PHP files). When generated automatically, the generated output has the same look and feel across all major browsers. It provides all the controls you’d expect in an HTML form and, additionally, date/time pickers, captcha, and AJAX-like file upload controls.
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.
Image.class is a PHP class that can be used to generate images with graphic primitives defined programmatically. It can create an empty image with a given size or load an existing image from a JPEG, PNG, or GIF image. The class can render graphic primitives in the image like drawing a text string with optional border, copying parts of the image to another position, drawing ellipses, rectangles, and lines, and scaling the image to a given size. The generated image can be saved also in JPEG, PNG, or GIF formats.
Zebra_MPTT is a PHP class that provides an implementation of the modified preorder tree traversal algorithm. It provides methods for adding nodes anywhere in the tree, deleting nodes, moving and copying nodes around the tree, and for retrieving information about the nodes. It uses table locks to ensure that database integrity is always preserved and that concurrent MySQL sessions don’t compromise data integrity. A caching mechanism ensures that regardless of the type or the number of retrieval operations, the database is read only once per script execution.
