Information about PHP
Hello,
PHP is actually Hypertext Preprocessor.PHP is a computer scripting language.PHP is a simple yet powerful language designed for creating HTML content.PHP is originally designed for producing dynamic web content as it is the best for the task.As there is no formal specification the main implementation of PHP is now produced by the PHP group and serves as the de facto standard for PHP. PHP was originally created by Rasmus Lerdorf in 1995.THe PHP is considered as a free software by the Free Software Foundation and PHP is released under the PHP license.PHP is a scripting language that is widely used and is a general language which is used for web development.Also ,it can be embedded into HTML .PHP is used in the web server as it takes in the PHP code and gives out the web pages as a result.Recently the PHP 5.2.6 was released on 1 may ,2008 which is considered to be the most recent major release of PHP.PHP is installed on more than 1 million web server and more than 20 million websites.PHP can be installed on most Dedicated servers and on almost every platform or operating system free of charge.
PHP can be used in three different ways :-
- Server side scripting
Dynamic web content was the reason that the PHP was designed and it is suitable for the task.You need a PHP parser and to generate HTML and to send the documents you require a web server.XML documents,Flash animations ,PDF files ,graphics and more were also generated by PHP and it lately became popular for this.
- Command – line scripting
Much like Perl,awk or the Unix shell PHP can also run scripts from the command line.You might use the command-line scripts for system administration tasks,such as backup and log parcing.
- Client-side GUI Applications
You can write full-blown,cross platform GUI Application in PHP by simply using PHP-GTK (http://gtk.php.net)
PHP’s principal focus is server-side scripting and it is originally designed for this pupose only.PHP is similar to Microsoft’s ASP.NET system ,Sun Microsystems’ Java Server Pages and mod_perl as these are also some of the other server-side scripting languages that provide dynamic content from a web server to a client and the PHP also does the same.Cake PHP, PRADO, Symfony and Zend Framework are some of the frameworks offering features similar to other web application frameworks that provide building blocks and a design structure to promote rapid application development (RAD).These are also attracted to PHP.The LAMP architecture has become popular in the web industry as a way of deploying web applications.PHP is commonly used as the P in this bundle alongside Linux, Apache and MySQL, although the P may also refer to Python or Perl. PHP was recorded as the most popular Apache module as in April 2007 over 20 million Internet domains were hosted on the PHP installed Dedicated servers. Significant websites such as the user-facing portion of Facebook and Wikipedia[mediawiki] are also written in PHP.
