PHP code can be used to create images, query databases, write and read files and talk to remove servers. Because PHP is combined with HTML in the script, the user’s browser does not know if PHP is used because the browser just sees HTML.

Another reason for the popularity of PHP is its ability to work in an extensive list of databases and web servers. Gone are the days when large websites were built with individual HTML pages. PHP makes it easier for webmasters to make the most of their powerful databases and completely personalize their websites.  Choose reliable web hosting and a PHP web design for a modern, interactive website your customers will appreciate.
