The use of PHP as server side application coding ensure a complete portability on any server and desktop platform.

PHP is a guarantee for compatibility across OS's standards: original from Unix systems, it can be easily installed and managed on Windows machines and comes in base packages with any Linux distribution. PHP has also support for most of the web servers today. This includes Apache, Microsoft Internet Information Server, Personal Web Server, Netscape and iPlanet servers, Oreilly Website Pro server, Caudium, Xitami, OmniHTTPd, and many others. For the majority of the servers PHP has a module, for the others supporting the CGI standard, PHP can work as a CGI processor.

So with PHP, you have the freedom of choosing an operating system and a web server. Furthermore, you also have the choice of using procedural programming or object oriented programming, or a mixture of them. PHP5 introduces a new complete object model.

With PHP you are not limited to output HTML. PHP's abilities includes outputting images, PDF files and even Flash movies generated on the fly. You can also output easily any text, such as XHTML and any other XML file. PHP can autogenerate these files, and save them in the file system, instead of printing it out, forming a server-side cache for your dynamic content.

One of the strongest and most significant features in PHP is its support for a wide range of databases. Writing a database-enabled web page is incredibly simple. The following databases are currently supported:

» Adabas D

» InterBase

» PostgreSQL

» dBase

» FrontBase

» SQLite

» Empress

» mSQL

» Solid

» FilePro (read-only)

» Direct MS-SQL

» Sybase

» Hyperwave

» MySQL

» Velocis

» IBM DB2

» ODBC

» Unix dbm

» Informix

» Oracle (OCI7 and OCI8)

» Ingres

» Ovrimos

We also have a DBX database abstraction extension allowing you to transparently use any database supported by that extension. Additionally PHP supports ODBC, the Open Database Connection standard, so you can connect to any other database supporting this world standard.

PHP also has support for talking to other services using protocols such as LDAP, IMAP, SNMP, NNTP, POP3, HTTP, COM (on Windows) and countless others. You can also open raw network sockets and interact using any other protocol. PHP has support for the WDDX complex data exchange between virtually all Web programming languages. Talking about interconnection, PHP has support for instantiation of Java objects and using them transparently as PHP objects. You can also use our CORBA extension to access remote objects.

PHP has extremely useful text processing features, from the POSIX Extended or Perl regular expressions to parsing XML documents. For parsing and accessing XML documents, PHP4 supports the SAX and DOM standards, and you can also use the XSLT extension to transform XML documents. PHP 5 standardizes all the XML extensions on the solid base of libxml2 and extends the feature set adding SimpleXML and XMLReader support.

While using PHP in the e-commerce field, you'll find the Cybercash payment, CyberMUT, VeriSign Payflow Pro and MCVE functions useful for your online payment programs.

At last but not least, we have many other interesting extensions, the mnoGoSearch search engine functions, the IRC Gateway functions, many compression utilities (gzip, bz2), calendar conversion, translation...

As you can see this page is not enough to list all the features and benefits PHP can offer. Read on (<http://www.php.net/manual>) in the sections about installing PHP, and see the function reference part for explanation of the extensions mentioned here.
