PHP (Hypertext Preprocessor) is one of the almost popular means of refined HTML and PHP forms. Originally it was created by Rasmus Lerdorf in 1995 and stood for Personal Homepage. It began in 1994 as a set of Green Gateway Interface binaries written in the C programing language. The Danish/Greenlandic programmer Rasmus Lerdorf created these Personal Homepage Tools to exchange a small set of Perl scripts exploited to maintain his personal homepage. The tools served for displaying his resume and recording how often traffic his page was receiving.

PHP is a scripting language. It was designed for producing dynamic web pages. Now it can admit a command line interface capacity and can be exploited in standalone graphic applications. It is similar to other server-side scripts that offer dynamic content from a web host to a client, such as Microsoft's Active Host Pages, Sun Microsystems' JavaServer Pages, and mod_perl. PHP executes hundreds of base functions and thousands more via extensions.

The PHP Group produces the primary effectuation of PHP which ...
... serves as the de facto standard for PHP, because there is no formal specification now. PHP Group provides the complete source code for users to build, customize and extend for their own use. It is considered a free software cathartic under the PHP Licence. But it is uncongenial with the GNU General Public License (GPL) as there are restrictions on the usage of the term PHP.

PHP is a widely-exploited general-purpose scripting language that can be embedded into HTML. It mostly runs on a web host and creates web pages taking PHP code. It is also exploited for control-line scripting and customer-side GUI applications. It works on most web servers, operating systems and platforms free of charge. PHP can be used with many relational database management systems. Now it functions on more 20 million websites and 1 1000000 web servers.

PHP can be compared to a filter as it takes input from a file or flow containing text and/or PHP instructions and outputs another data; HTML is the almost common output. It can automatically identify the language of the user.

One who has ever created any HTML page or start dynamic web programing, has already met with forms. Forms are especial components which allow the website visitors to add info on the HTML page.

A PHP form on a web page allows a user to enter data that is sent to a server for processing. E.g., about each company web site contains a contact form, so that visitors can send a content to the site owner. Such a contact form usually contains various fields - for the visitor's name, for the email address and one for the primary message. PHP forms resemble paper forms because internet users fill out the forms using checkboxes, tuner buttons, or text fields. For example, the forms can be used to insert shipping or credit card data to order a product or can be used to retrieve data.
