PHP is a server-side scripting language that enables web development, and can be used for all types of programming. Its popularity has exploded in recent years. So much so that the last estimate of PHP installations and site designs indicated that PHP was used to power nearly 250 million web sites around the world. There has been an explosion of PHP Development frameworks, like CakePHP, Zend Framework, Symphony and others, and these frameworks and tools add significant value for developers. PHP developers can also leverage the large global development community to discuss issues and find tips and tricks to make the development process easier, more flexible and more successful.The PHP hypertext preprocessor language is interpreted by a web server, and generates a page, or a set of pages using PHP embedded codes within the HTML document. One of the reasons PHP is so popular among developers is that the PHP license is free to use and it can be deployed on nearly all web servers and on most platforms and operating systems without any licensing costs.
