PHP is a general-purpose scripting language that is especially suited for dynamic web development. It is robust, open source, and commonly deployed on most web servers, operating systems, and platforms. PHP's primary strengths are its ability to communicate with many database systems, to manipulate the information, and serve the custom content to web pages. Coda actively encourages two way communication, between yourself and your audience, by using PHP to broadcast, collect, and store information in our advanced web design projects.
