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.
This is a PHP class that attempts to validate a given e-mail address at three levels: matching the address against a RFC compliant regular expression, verifing the existence of the destination SMTP server by verifying the respective DNS MX record, and connecting to that server to see if the given address is accepted as a valid recipient. The class also features a debugging output option that lets you see the remote SMTP server connection and data exchange dialog to see the real cause why an apparently valid address may not be accepting messages.
PHP HTTP protocol client is a PHP class for making HTTP requests. It can establish connections via SOCKS or proxy servers and establish secure connections (HTTPS) with optional SSL client certificates. It supports HTTP Basic, HTTP Digest, and NTLM (Windows or Samba) authentication mechanisms. It submits POST requests with user-defined form values, file uploading, or with user-defined request bodies. It handles cookies and automatic redirection handling. There is an addon class that logs in to Yahoo! and executes actions on behalf of the user, like exporting the address book or sending invitations to Yahoo! groups.
Metabase is a DBMS-independent PHP API to access SQL databases. It supports MySQL, PostgreSQL, Oracle, Microsoft SQL server, Microsoft Access, ODBC, Interbase, Informix, MiniSQL, and SQLite. It supports nested transactions, blobs, and prepared queries. It can install database schemas defined in a DBMS independent XML format that describe tables, indexes, primary keys, and auto-increment sequences. It is also able to upgrade a database to a new schema without affecting the data that was stored since it was installed or upgraded for the last time. There is also schema reverse engineering support.
SMTP client class is a PHP class that connects to a mail server to send messages. It can relay message delivery to a defined server or directly deliver messages to a recipient's server for urgent message delivery. It supports secure connections with SSL or starting TLS after the connection is established, connection timeouts, authentication using PHP SASL class (PLAIN, LOGIN, CRAM-MD5, NTLM), POP3 before SMTP delivery authentication, and takes advantage of the SMTP PIPELINING extension to buffer SMTP commands, providing much faster queueing of messages when delivering to a large number of recipients (bulk mail).
Metastorage is a PHP data access object generator compiler tool. It implements an object persistence API from a description in an XML format named CPML. The persistent object classes implement object-relational mappings, so developers do not have to write SQL manually. It features an object query language for specifying conditions for querying objects, generation of classes for producing reports, generation of classes to manage templated Web forms for creating new persistent objects, and generation of UML class diagrams. It can be run from the command line or from a Web interface.
XML parser class is a PHP class that parses arbitrary XML input and builds an array with the structure of all tag and data elements. Optionally it can keep track of the positions of each element to locate elements that may be contextually in error. Supports a parsed file cache to minimize the overhead of parsing the same file repeatedly. Optimized parsing of simplified XML (SML) formats ignoring the tag attributes.
RSS Writer Class is a PHP class that can generate RSS (Rich/RDF Site Summary) XML documents. It extends the XML Writer class to generate XML-RSS documents. It features simplified definitions of channel and item properties, support for defining optional channel graphic images and search form text inputs, support for RSS specification versions 0.9, 0.91, 1.0, and 2.0, support for using namespace modules to extend the document property set, and an optional XSL stylesheet example to automatically view RSS documents as HTML pages in XML capable browsers.
With the PHP Text File Interface (Txt-Db-API) you can access normal text files like an SQL Database. You don't need any special database software on the Web server, yet you can still use SQL calls. You can use the API to create, query, change, or delete SQL tables, and you don't have to bother with the text files themselves; almost everthing can be done with the supported API calls. The Txt-Db-API is object-oriented and very simple to use.
freshmeat Project Query Class queries freshmeat.net and retrieves information on projects with records there. It features retrieval of project information from records provided by freshmeat in XML, parsing of project XML records to extract all the relevant data, and caching of retrieved project information in disk files for at least the next day to avoid retrieving the same data again before it could have been updated.
