PHP Table class is a simple but powerful table renderer that consists of data aquisition and rendering components. It allows you to easily display the results of an SQL query or a PHP array as a formatted HTML table with stylesheet support, ordered columns, and numeric totals. A powerful class inheritance method provides a great deal of flexibility. It is also possible to output tab-separated records.
PHP Comment Class is a simple, reusable comments engine which utilizes the PHP Table and Form classes. Backing into a MySQL database (or any other persistent store provided by Table or Form), it provides a set of Form and Table children which, when called, generate a comments engine with input validation and stylesheet support.
PHP Voice (formerly known as PHP VXML) contain four classes that assist in developing voice application using PHP. It supports Speech Synthesis Markup Language 1.0, Speech Recognition Grammar Specification 1.0, Voice Browser Call Control: CCXML 1.0, and Voice Extensible Markup Language (VoiceXML) 2.0.
DBX works using XML files as its native format. The database can be queried using standard SQL queries. DBX is the smallest, platform independent DBMS, and is extremely easy to migrate to. For small databases, it is a good substitute for MySQL, Oracle, etc. The added advantage is that it saves the data as neat, readable, XML files, allowing easy compatibility.
Error Handler provides a custom interface to error handling in PHP. Several report formats can be used to reveal what circumstances led to a certain error. One for logging, one for display, and one for redirection. It captures the errors and captures (to a customized level) the context and variables surrounding the source of the error and neatly organizes them as a series of reports.
MiniXML provides a simple API used to generate and parse XML. Its advantages are ease-of-use and the fact that no additional libraries are required. The set of classes allows developers to access XML data and create valid XML output with a tree-based hierarchy of elements. The PHP and Perl classes are independent and do not require any additional libraries.
