PHP is a server-side scripting language that processes and generates HTML codes in response to client’s request.PHP’s origin dates back to 1995 when an independent software development contractor named Rasmus Lerdorf developed a Perl/CGI script that enabled him to know how many visitors were reading his online résumé. His script performed two tasks: logging visitor information, and displaying the count of visitors to the web page. Because the Web at the time was still a fledgling technology, tools such as these were nonexistent. Thus, Lerdorf’s script generated quite a bit of interest. Lerdorf began giving away his toolset, dubbed Personal Home Page (PHP).
Back in the early 1990s, web pages consisted of nothing but text. Things didn’t stand still for long, and it soon became possible to add images and scrolling text. But even if some things moved around the page in an irritating way, everything on the Web was static in the sense that the content was fixed at the time the page was created. Genuinely dynamic features began to be added around 1995 with the help of two distinct types of technology: Client-Side and Server-Side.
