ADODB is a set of advanced PHP database abstraction classes. It supports MySQL, PostgreSQL, Interbase/Firebird, Informix, Sybase SQL Anywhere, Oracle, MS SQL 7 and 2000, SAP DB, Sybase, DB2, FrontBase, Foxpro, Access, Netezza, LDAP, ODBTP, ADO, and generic ODBC. A metatype system is built in, making it possible to figure out that types such as CHAR, TEXT, and STRING are equivalent in different databases. It also features portable database creation, database-backed session support (with encryption), SQL performance monitoring, and database health checks.
Xapian is a search engine library, scalable to collections containing hundreds of millions of documents. It's written in C++ with bindings for Perl, Python, PHP, Java, Tcl, C#, Ruby, and Lua. It is a highly adaptable toolkit that allows developers to easily add advanced indexing and search facilities to their own applications. It supports the Probabilistic Information Retrieval model and also a rich set of boolean query operators. Omega is a Web search application built upon the Xapian library. It can index a Web server's document tree (including HTML, PDF, OpenOffice, MS Word/Excel/Powerpoint/Works, WordPerfect, RTF, PS, etc.), or data exported from arbitrary sources (e.g. SQL databases).
PHP OAuth API authorizes user access using the OAuth protocol. It abstracts OAuth 1.0, 1.0a, and 2.0 in the same class. It provides built-in support for popular OAuth servers: 37Signals, Amazon, Buffer, Bitbucket, Box.net, Discogs, Disqus, Dropbox with OAuth 1.0 and 2.0, Etsy, Eventful, Facebook, Fitbit, Flickr, Foursquare, github, Google with OAuth 1.0a and OAuth 2.0, Instagram, LinkedIn, Microsoft, Rdio, Reddit, RightSignature, Salesforce, Scoop.it, StockTwits, SurveyMonkey, Tumblr, Twitter, VK, Withings, Xero, XING, and Yahoo!. Every other OAuth server is supported by setting an endpoint URLs and other parameters using specific class variables or an external JSON configuration file. The class can also send requests to an API using the previously-obtained OAuth access token. For servers which support offline access, the class can renew expired tokens automatically using refresh tokens.
The adventure PHP framework (APF) is a utility to implement object oriented and generic PHP Web applications. It allows the developer to create programs in compliance with approved software design patterns, and the code base already has answers to many everyday problems. The framework cannot be described as an application that only has to be configured, but rather as a technical basis and design guide for the design of software. Further, it introduced many concepts and efficiency tools already well known in the Java community.
PHPGrid generates fully-functional grids with minimal coding, with add, edit, del, auto-filter, search, sort, page, grouping, export, custom add/del calls, grid-subgrid, multiple databases, multiple themes, and much more. It saves development time and effort for creating repetitive CRUD functions. The custom SELECT query option is useful for cross table data and report generation. It supports all major databases.
Turck MMCache is a free PHP accelerator, optimizer, encoder, and dynamic content cache. It increases performance of PHP scripts by caching them in a compiled state, so that the overhead of compiling is almost completely eliminated. It also uses some optimizations for speeding up PHP scripts' execution. It typically reduces server load and increases the speed of PHP code by 1-10 times. It is tested with PHP 4.1.0-4.3.3, and Apache 1.3 and 2.0 under Linux and Windows.
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.
