PHP is an open source scripting language which is used on a server side and is used to interpret the scripts at the runtime. They are basically used to make the performance of the website better. It is used with static sites, dynamic websites as well as web apps. Even big technical brands such as Wikipedia, Tumblr, Facebook etc.
It is so adjusting langauge that you can easily add an HTML code in the PHP script whereas reverse is not true. It takes the data from the user and produces the desirable output.
To learn this language one needs to know HMTL, CSS as well as JavaScript thoroughly. Because since this is a backend language so it will be added to a site only after adding frontend of the site.
PHP is accompanied by MySQL, where MySQL database is basically a storage scape which stores the data that is entered by the user and returns it as the command says.
