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.
Amazon S3 Stream Wrapper is a PHP class that acts as a stream wrapper that can be used to get and send files to Amazon S3 (Simple Storage Service). It sends HTTP requests to access the Amazon S3 Web services API in order to store and retrieve files just by using fopen('s3://...') calls and using regular fwrite and fread functions to send and retrieve file contents from Amazon S3 servers. This stream wrapper class can also delete files, and create, list, and delete directories.
File exchange Protocol can be used to store and retrieve files in a remote repository server using HTTP. It can access a remote server using HTTP requests with authentication to protect the access to the remote files. The class can perform requests to create, write, read, and delete remote files. It can also create, list, and delete directories. It implements a stream wrapper interface to make it possible to access the remote files with PHP functions like fopen('fep://...') and other PHP file and directory manipulation functions. You can also apply a Stream Wrapper that allows you to mount a remote filesystem.
c_xml is a class that can convert between XML files and arrays or strings. It can parse an XML file into a DOM document object, so it can be returned as an array or displayed using a XSL stylesheet. The parsed XML document can also be manipulated to add, change, or remove nodes. Nodes may be searched using XPath. The resulting document can be regenerated in XML format.
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.
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.
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).
