Unpopular, deprecated features such as Magic Quotes, register_globals, safe_mode, and the HTTP_*_VARS variables will disappear in PHP 6.Īlthough PHP is still primarily used for server-side generation of Web pages, it can also be used to perform command-line scripting or to create graphical applications with the help of GTK+. The most significant change will be native support for Unicode. PHP 6 has been in development since October of 2006. integrated SOAP support (see the image at right).exception handling using a try.catch structure.support for new MySQL features (see the image at right).Among the many new features in PHP 5 are: PHP 5 was released in July 2004, with the updated Zend Engine 2.0. Maintenance releases of PHP 4 are still available, primarily for security updates. In terms of features, PHP 4 added references, the Boolean type, COM support on Windows, output buffering, many new array functions, expanded object-oriented programming, inclusion of the PCRE library, and more. PHP is a scripting language web developers use to create dynamic websites. PHP 4 featured improved speed and reliability over PHP 3. Stands for 'PHP: Hypertext Preprocessor,' a recursive acronym. PHP 4 was released in May 2000, with a new core, known as the Zend Engine 1.0. (This is an example of a recursive acronym: where the acronym itself is in its own definition.) In 1998, PHP 3 was released, which was the first widely used version. The acronym was formally changed to PHP: HyperText Preprocessor, at this time. Two programmers, Zeev Suraski and Andi Gutmans, rebuilt PHP's core, releasing the updated result as PHP/FI 2 in 1997. Lerdorf combined PHP with his own Form Interpreter, releasing the combination publicly as PHP/FI (generally referred to as PHP 2.0) on June 8, 1995. For this reason, PHP originally stood for "Personal Home Page". PHP was written in the C programming language by Rasmus Lerdorf in 1994 for use in monitoring his online resume and related personal information. It is an open source technology and runs on most operating systems and with most Web servers. PHP takes most of its syntax from C, Java, and Perl. PHP code is normally run in plain-text scripts that will only run on PHP-enabled computers (conversely programming languages can create standalone binary executable files, a.k.a. As a scripting language, PHP code requires the presence of the PHP processor. The first part of this definition means that PHP code can be interspersed with HTML, making it simple to generate dynamic pieces of Web pages on the fly. furthermore, we’ll get through this syntax later.PHP is an "HTML-embedded scripting language" primarily used for dynamic Web applications. The open-source nature of the code further means that any developer, anywhere, can inspect the code tree, spit errors, and suggest possible fixes, this produces a stable, robust product wherein bugs, once discovered, are rapidly resolved – sometimes within a few hours of discovery.įirst of all, let’s get started to our first tutorial with an example: PHP Hello World Program This reduces software development costs without affecting either flexibility or reliability. PHP is an open source project – the language is developed by a worldwide team of volunteers who make its source code freely available on the Web, and it may be used without payment of licensing fees or investments in expensive hardware or software. How PHP works? Server, Clients and the Preprocessor communications Index.php – Often the default file to be loaded when a client Web browser requests a directory from a PHP-enabled Web server. It may include PHP functions that can process online forms, get the date and time, or access information from a database, such as a MySQL database. What actually is a PHP file?Ībc.php – A file is a webpage that contains PHP (Hypertext Preprocessor) code. PHP Programs are portable between platforms.Īs a result, an application developed on, say, Windows will typically run on UNIX without any significant issues. Here are some of the most popular PHP frameworks.Īvailable for UNIX, MICROSOFT WINDOWS, MAC OS, and OS/2. PHP frameworks are built on an architecture that simplifies the process of building a complex application within a short period of time. But one has basic knowledge about computer programming and its procedures. This tutorial is developed for beginners who are completely unaware of the PHP concept and its powers. PHP 3.0 was introduced in 1998 and PHP 4 was introduced in 1999 and released in 2000. Later on, in 1997 a stable version of PHP was released, that was PHP 2.0. It is the successor of product name PHP/FI. PHP was originally created by a developer named Rasmus Lerdorf way back in 1994.
