A scripting language designed for creating dynamic web pages is called PHP. It has emerged to include a command line interface capability and is generally used in standalone graphical applications. PHP, either signifies Personal Home Page or for PHP Hypertext Preprocessor. Since the person who innovated the language calls it Personal Home Page, it is a fair bet as to which is the proper rendition of the acronym.
PHP, as discussed earlier is a scripting language: a programming language used to write scripts or small interpreted programs. It is a server-side scripting language whose main purpose is to produce HTML content. With the existing direction of the Web, it is easily being tailored to writing out all forms of XML content as well.
It was originally invented as a set of server-side modules to perform some particular Web-server tasks on small, Unix-based Web servers. This is one of the personal aspects that makes it so special. Since then PHP has developed beyond the labor of one man writing some tools for his own use, it has emerged into one of the most accepted server-side scripting languages in the Web.
Three things make PHP most popular among people of all ages, country, class and gender who want to learn and inculcate the computing ideas among themselves. The first is that it is easy: simple to implement, easy to study, and easy to employ. The next is that it is free. The third is that it runs on approximately any Web server on more or less on any platform presently available.
What goes behind is a short introduction to PHP. We will gaze at the record of PHP and what it can do. We will also glance at an easy piece of sample code as part of a typical hello world assignment.
While PHP was at first created by Rasmus Lerdorf in 1995, the chief implementation of PHP is now fashioned by The PHP Group and serves as the de facto standard for PHP as there is no recognized specification. PHP is gratis software released under the PHP License; however it is unsuited with the GNU General Public License (GPL), mainly because of the restrictions on the usage of the term PHP.
PHP can be embedded into HTML and it generally runs on a web server, thereby taking PHP code as its input and creating web pages as output. It can be positioned on most web servers and on almost all operating system and platform free of charge. What is PHP is thus clear from the above discussion. PHP development according to the survey, PHP is installed in more than 20 million websites and 1 million web servers.
