This is fairly hard to do. PHP has nearly endless possibilities.PHP can be an Object-Oriented or Function-Oriented programming language. Though PHP is mostly used for web design, it is possible to use PHP outside of the internet, but this is complicated.PHP can do almost anything from performing simple arithmetic calculations, to providing uses with information, user accounts, and more. You can edit pictures with PHP, look up IP addresses, and handle different strings. You can even pull and alter information of mySQL databases!I highly recommend PHP, but it cannot be used if you don't have PHP installed. PHP is a free software, and can be download from php.net. You can use PHP on the internet though, as long as it is installed on that particular web server. Most free hosting websites already have PHP installed.
