This module supports 4 slot coin acceptors using the ABCD method to control them core=PHP interpreter body crack=These functions allow you to use the CrackLib library to test the strength of a password. The strength of a password is tested by that checks length, use of upper and lower case and checked against the specified CrackLib dictionary. CrackLib will also give helpful diagnostic messages that will help to strengthen the password ctype=This extension functions allow to check if a symbol or a string belongs to a certain set of symbols while taking into account regional settings curl=Interface to a powerful library for making HTTP, FTP and other requests and handling the output date=These functions allow you to get the date and time from the server where your PHP scripts are running. You can use these functions to format the date and time in many different ways. The date and time information is internally stored as a 64-bit number so all conceivably useful dates (including negative years) are supported. The range is from about 292 billion years in the past to the same in the future dba=These functions build the foundation for accessing Berkeley DB style databases. This is a general abstraction layer for several file-based databases. As such, functionality is limited to a common subset of features supported by modern databases such as Oracle Berkeley DB dbase=These functions allow you to access records stored in dBase-format (dbf) databases. dBase files are simple sequential files of fixed length records. Records are appended to the end of the file dbx=The dbx module is a database abstraction layer. The dbx functions allow you to access all supported databases using a single calling convention. The dbx-functions themselves do not interface directly to the databases, but interface to the modules that are used to support these databases. The currently supported databases are MySQL, ODBC, Oracle (oci8), MS SQL Server, PostgreSQL, FrontBase, Sybase-CT and SQLite. The module-dependencies are only for the databases you wish to use dom=The DOM extension allows you to operate on XML documents through the DOM API with PHP 5 doublemetaphone=The Double Metaphone algorithm by Lawrence Philips allows a word to be broken down into its phonemes eaccelerator=PHP accelerator derived from the MMCache extension for the PHP programming language. eAccelerator provides a bytecode cache eio=This extension provides asynchronous POSIX IO by means of libeio C library enchant=Enchant is the PHP binding for the Enchant library.

Considered deprecated as of PHP 5.3 in favour of PCRE extension exif=Provides access for images EXIF metadata fileinfo=This module functions try to determine a file content type and encoding by means of analyzing certain magic bytes sequences at certain positions of the file. This is not truly reliable method but for most situations that will do filter=This extension filters data by either validating or sanitizing it. This is especially useful when the data source contains unknown (or foreign) data, like user supplied input. For example, this data may come from an HTML form. ftp=This module functions provide remote servers access by FTP protocol. functional=This module functions provide a set of functions and primitives for functional programming gd=Functions for working with images including images streaming gender=Port of the gender.c program to find out the gender of firstnames.

It is especially useful with fastcgi (ISS5,6,7, lighttpd, etc.) huffman=Huffman compression belongs into a family of algorithms with a variable codeword length. That means that individual symbols (characters in a text file for instance) are replaced by bit sequences that have a distinct length. So symbols that occur a lot in a file are given a short sequence while other that are used seldom get a longer bit sequence iconv=This extension provides interface to encodings conversion library iconv idn=Conversion to and from Internationalized Domain Names igbinary=Igbinary is a drop in replacement for the standard php serializer. Instead of time and space consuming textual representation, igbinary stores php data structures in a compact binary form.

It can deal with RFC 822 and RFC 2045 (MIME) compliant messages mbstring=Provides multibyte specific string functions that help you deal with multibyte encodings in PHP. In addition to that, mbstring handles character encoding conversion between the possible encoding pairs. mbstring is designed to handle Unicode-based encodings such as UTF-8 and UCS-2 and many single-byte encodings for convenience mcrypt=This is an interface to the mcrypt library, which supports a wide variety of block algorithms such as DES, TripleDES, Blowfish (default), 3-WAY, SAFER-SK64, SAFER-SK128, TWOFISH, TEA, RC2 and GOST in CBC, OFB, CFB and ECB cipher modes. Additionally, it supports RC6 and IDEA which are considered non-free. CFB and OFB are 8bit by default mhash=Mhash can be used to create checksums, message digests, message authentication codes, and more msgpack=MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON but faster and smaller. For example, small integers (like flags or error code) are encoded into a single byte, and typical short strings only require an extra byte in addition to the strings themselves. If you ever wished to use JSON for convenience (storing an image with metadata) but could not for technical reasons (encoding, size, speed...), MessagePack is a perfect replacement mysql=This module functions let you work with MySQL. Do not use it for new code, use mysqli or pdo_mysql instead mysqli=This extension gives a user access to functionality provided by MySQL server 4.1 and above ncurses=ncurses (new curses) is a free software emulation of curses in System V Rel 4.0 (and above).
