The PHP, defines as a programming language for the fast creation of dynamic contents of Web sites, as they are the forums, blogs, systems of the news, among others. Also, it creates independent graphical applications of the navigator and applications for servants. It is a language of script within the HTML.
The main function of the PHP is to allow to the interaction of the page Web with the visitor who could have realised changes in her, and each user who enters the page will be able to see the information previously modified. Its name comes from the abbreviation of concept PHP Preprocessor Hypertext. It is an acronym, that is to say, the initials of each word crawl to give rise to the definitive term.
This computer program was created in Perl year 1994 by Rasmus Lerdorf to control who visited their vital curriculum in the Web besides keeping and registering the data that its page received. In that time they called Personnel Home Pages, translated as “Personal Tools of Work” then only to that were limited. In that then PHP it had not acquired the importance that it has at the moment. Nevertheless, with time, one went away perfecting, becoming universal and more complex in its duties, mainly by the work that the Israelis Surasky and Gutmans in 1997 carried out. Little by little the newness went reaching million users.
Nowadays, the PHP presents/displays essential characteristics make that it be so effective. Multipataforma owns a language, that is to say, a software that works in diverse platforms; connection and contributes with a great number of data bases like MySQL, Oracle, Informix, among others; capacity to expand potentially by its great amount of modules; with external libraries of functions; he is free (open source or open code) and therefore reasonable for it wishes which it.
For the use of this program, in the first place it is required of a servant who has supported PHP. Soon the client must create the archives and to keep them in the directory Web and the servant sends the request to the PHP interpreter analyzes that them and compiles. The result is sent to the servant and the client. The PHP, concluded the work, is translated in abbreviation HTML (the standard for the codification of pages Web; that is to say, the PHP internamente does the work in the servant, to give to the user or navigator Web the result in standard code)
The PHP at present very has been demanded by which they participate actively in the world of the computation, mainly by his power, high performance, easy learning, shortage of consumption of resources, and most important, their gratuity; programs of manufacturers as Microsoft or Macromedia at present lacks this characteristic.
